Analyst · various factors included in our most recent press release, most recent 8-K, 10-Q and annual report, which are on file with the SEC
Thank you, Randy. Good morning, everyone. Thank you for joining me today. What a year. I believe that from now -- that years from now, many of us will reflect upon 2020 as being one of the most unique, unpredictable and challenging business environments of our career. My sincerest gratitude goes out to our 195,000 plus associates working in more than 15,600 Dollar Tree and Family Dollar stores and in 26 distribution centers and to our field leadership teams as well as our store support team here in Chesapeake, Virginia. Your commitment and dedication to protect and serve our customers is critical to our company's success. As an essential retailer in the value segment, we will continue to be part of the solution for millions of households across North America.
Additionally, I would like to recognize our business partners, both supply chain and suppliers, for their efforts to support our business throughout the year. In 2020, we exceeded $25 billion in annual sales for the first time, and we have a long runway of growth ahead of us. As our business grows, so does the need and support from each of our business partners. We appreciate your continued support.
The recent trends have been encouraging. COVID cases are on the decline, and vaccinations are on the rise. However, we will continue to be relentless in our efforts to protect each other until this pandemic is behind us.
I am very pleased with the team's operating performance for the fourth quarter, highlighted by solid same-store sales increase, improved gross margin and expense leverage. The team delivered EPS increase of 310% compared to the prior year's quarters or 19% when adjusted for discrete charges in the prior year. Our results included a 4.9% enterprise comp increase, an 80 basis point improvement in gross profit margin and a 90 base increase in operating profit margin when compared to the prior year's adjusted numbers.
Our Dollar Tree segment delivered another quarter of positive same-store sales with a 2.4% increase. January was the strongest month of the quarter, followed by November. In fact, January was our strongest monthly comp since April of 2019. December was slightly negative as store traffic was impacted by an escalation in COVID cases, resulting in expanded lockdowns and significantly fewer holiday social gatherings among families, companies, churches and schools. As we have seen in the onset of the pandemic, sales were again driven by average ticket, which increased 17.9% as shoppers continue to consolidate trips. Comp transaction count declined 13.1%.
We delivered a 36.1% gross margin, and Dollar Tree's operating margin, which included $13.8 million in COVID-related costs, came in at 16% operating income. Categories performing well included crafts, seasonal, household products, floral, kitchenware and beauty and eyewear. Building on the continued success of craft assortment, we completed the rollout of Crafter's Square to all U.S. Dollar Tree stores in January. Inspiring the creativity of our customers is at the core of Dollar Tree, and we are thrilled to provide an even broader assortment of art and crafts supplies at tremendous values. With our $1 fixed price point and more than 7,500 U.S. store locations, Crafter's Square presents customers with an unlimited solutions for current learn-from-home and work-from-home environment.
Additionally, terrific opportunity exist for DIY home projects and decor, crafts for the entire family, seasonal decorations and handmade gifts. Our shoppers love the expanded assortment, which is validated by the excitement Crafter's Square is generating across social media platforms, including YouTube and Instagram.
Regarding our Dollar Tree Plus!, our shoppers love the values, and we exceeded our initial sales plan for the fourth quarter. We had great sell-through on our seasonal products, on our toys and household consumables. We are on schedule to kick off the previously announced expansion of Dollar Tree Plus! this month. We are expanding multi-price assortment from the current base of 120 stores to a total of 500 stores and will be completed by August. Additionally, we are capturing great buying synergies as the majority of the $3 and $5 merchandise for the DT Plus! will be offered in both banners.
Family Dollar sales highlights for the quarter included an 8.1% comp increase, comprised of a 21.9% expansion in average ticket, partially offset by 11.3% decline in transaction count. This is similar to the ticket traffic trip consolidation dynamic we have seen since Q1 of 2020.
Regarding the cadence of comps, all 3 months were positive, with January being the strongest month. As a reminder, all Family Dollar stores were closed on Christmas Day in 2020, which has impacted December comp results as approximately 5,600 stores were open for business the previous year.
January was Family Dollar's strongest monthly comp since May of last year. We saw solid sales across many of the discretionary categories that we have been focused on improving, including home decor, apparel, household cleaning, lawn and garden, party, beauty care and seasonal.
The consumables side of the business delivered another positive quarterly comp at 6.2%, and the discretionary comp was a strong 13.5% comp. In Q4, discretionary as a percent of net sales at Family Dollar increased 120 basis points to 26.2% of sales. Similar to recent quarters, based on third-party data, our market share in discretionary grew 2x faster than the remaining market in Q4. Late in 2020, we launched our initial test for produce and frozen needs at select Family Dollar stores, targeting markets where shoppers have fewer local grocery options. We want to provide shoppers with convenient access to basic produce items as well as beef, poultry and pork. We plan to expand our test in 2021.
We recently announced the expansion of our new partnership with Instacart platform across the U.S. Same-day delivery is another example of meeting the evolving needs of Family Dollar shoppers. The initial results have exceeded our expectations, and we continue to receive very positive feedback from shoppers. These transactions have materially higher average ticket, and we believe the Instacart platform is enabling us to broaden our dollar -- our Family Dollar customer base. Interestingly, in the first 3 weeks of the national rollout, more than 80% of Family Dollar stores had 1 or more Instacart transactions.
As always, our most important scorecards come from our shoppers. We are seeing considerable improvements in our customer satisfaction survey scores. For Q4, we saw record numbers across each of the 4 key categories: store cleanliness, product assortment, customer service and speed of checkout. In fact, each of these categories have shown improvement for 3 consecutive quarters. Contributors to these -- this success is an enhanced Family Dollar brand strategy program that clearly conveys expectations and examples to our store teams. And the chains' annual store manager turnover are at the best in over a decade. The improved customer satisfaction results gives us confidence that we will be able to retain shoppers that discovered or reengage with Family Dollar during the pandemic.
Regarding Dollar Tree Canada, the team delivered another solid quarter, exceeding its plan for sales, gross margin and operating income. From a real estate perspective, we completed more than 280 projects, including 124 new stores, 11 relocations, 106 Family Dollar renovations and 45 store closings. We ended the year with 15,685 stores.
We accomplished a great deal in 2020. Much of this was made possible by our 2019 initiatives that really set the stage to gain traction and momentum in 2020 and beyond. To quickly recap, in 2019, we consolidated our Dollar Tree and Family Dollar store support centers into 1 campus, greatly improving efficiencies through enhanced communication, collaboration and support. We made tremendous progress on Family Dollar store optimization initiatives by rebannering 200 stores, closing more than 400 stores and doubling the pace of our renovation program to more than 1,000 per year.
We also launched our initial test for Dollar Tree Plus!, and we realigned our leadership team to enhance and align the consistency of communication, strategies, process and workflows. For example, Dollar Tree and Family Dollar merchants went through 2020 in complete unison for buying calendars, buying trip meetings, planning dates and category performance reviews. This strength in alignment was very evident in the success of our recent virtual buying trip in January, which is our biggest buying trip of the year. These initiatives help build the foundation for 2020 performance.
The progress we have made at Family Dollar in the past despite the pandemic has been remarkable. We are benefiting from improved store conditions and better execution on initiatives, resulting in market share gains. We have also seen improved customer satisfaction scores, store turnover and shrink improvements. I am convinced that Family Dollar will exit the pandemic as a much stronger organization. This progress is why I'm more enthusiastic about the opportunities in 2021 and beyond, including the expansion of Dollar Tree Plus! and the growth of our new Combination Stores into small towns across America.
I will go into more detail on our plans for 2021 after Kevin speaks to the Q4 performance and our outlook. Kevin?
