Thank you, Melissa. Good morning, everyone, and thank you for joining us today. As many of you read this morning, we've continued to make very good progress and are delivering solid results.
During our third quarter, we had identical sales of 2.7%, and our adjusted EBITDA was $634 million. The Q3 identical sales was our eighth consecutive quarter of identical sales growth, and we grew market share during the quarter. In addition, the proceeds received from our sale-leaseback transactions have allowed us to significantly reduce our debt by over $1.8 billion this year and by over $3.1 billion since the end of fiscal 2017. This has reduced net debt leverage to 3x at the end of our quarter and significantly reduced interest expense, down $105 million year-to-date versus last year.
As many of you know, over the last few years, we have brought together iconic retail banners with rich heritage and a strong local following. We are now pivoting to the future and aspire to build deep and lasting customer relationships through an easy, exciting and friendly shopping experience. As I mentioned last quarter, we're focused on 4 main areas to grow our business.
The first is our stores, our core business and our foundation for growth and profitability. We're investing in multiple areas to enhance the customer experience and improve store performance. For example, we're expanding our self-checkout capabilities and enhancing our staffing capabilities in the checkout lanes. We're also exploring other innovative technologies to make the store shopping experience easy for our customers.
We're building on our already strong share in fresh and expanding into exciting new meal solution offerings. We're enhancing our pricing and promotions capabilities with more technology to improve sales and protect margins.
We're making our stores more productive by enhancing our ordering and staffing technologies so that we can ensure better in-stock conditions, excellence in display execution and even more friendly service through the deployment of our staff where and when it matters to the customer. We will continue to invest in remodeling our stores with a sharper focus on making our stores easy, exciting and friendly for shoppers.
Second is eCommerce, which includes online, home delivery and Drive-Up and Go pickup service. In the third quarter, our online sales grew 34%. And in many cases, we grew overall spend with existing in-store customers. In addition, we are expanding our Drive-Up and Go pickup service currently available in 548 stores and expect to expand to nearly 1,400 stores in the next 2 years.
Our growth in this area will be assisted by technology, with improved customer-facing websites, use of micro fulfillment centers or MFCs, as we'll call them later, and integration with third-party delivery services as we learn what customers prefer.
We recently launched 2 MFCs in the San Francisco Bay area, working with Takeoff Technologies. We're fulfilling customers' orders from these centers with 25,000 frequently purchased nonperishable items to choose from. The rest of the order is then completed in the local store.
As we ramp up, we're rolling this service out to additional surrounding areas and moving auto volume into our MFCs. Our learning -- early learnings indicate improved picking efficiency, better inventory management as well as improved on-time delivery, areas that ultimately drive productivity and improve customer satisfaction.
We plan to make -- continue to make disciplined investments to further enhance our customers' online shopping experience. Our customers can add and clip their personalized Just for U deals for great savings on their favorite products while placing their orders online. By providing personalized deals with greater savings and rewards, our loyalty programs increase the loyalty or stickiness of our customers and, in many cases, increase their overall household spend with us.
Our eCommerce offering provides great convenience every day, and we stepped up our efforts to serve our customers well during the holidays. For instance, at Thanksgiving, we provided great choices in main meal entrées with all the trimmings and entertaining inspiration ideas for a delicious feast for our customers and their families. As a result, our online orders and sales leading up to Thanksgiving for home delivery and Drive-Up and Go reached an all-time high.
The third is Own Brands where our innovation and expansion are key to strong sales. The Own Brands' portfolio with over 11,000 products is distinctive and it drives loyalty to our stores and online offerings as many of our products are unique and cannot be found elsewhere. Today, Own Brands consists of 9 primary brands, 4 of which exceed $1 billion in annual sales, including Lucerne, O Organics, Signature and Signature Café.
We continue to innovate and introduce new items to the portfolio, launching 675 new products year-to-date, with over 800 planned for the full year. For example, in the third quarter, we launched a Signature Reserve European cookie tin, Open Nature body lotion and O Organics Chickpea Spaghetti. We pride ourselves on great quality products to meet all lifestyle needs. Open Nature, our free-from brand, is a great example where customers are seeking cleaner and more eco-friendly ingredients. Sales continue to grow in our Open Nature brand, up 20.3% in Q3 compared to the prior year.
Overall, Own Brands continues to contribute to identical sales, and sales penetration reached a new high at 25.6% for the third quarter. We aim to grow our Own Brands penetration to 30% over time through increased merchandising and promotions in underpenetrated geographies and through the addition of new, innovative, high-quality products that appeal to our customers.
The fourth is our loyalty program that allows us to build our base of engaged shoppers and increased share of wallet. Our Just for U household registrations were up 25% in Q3 versus a year ago. As we continue to invest in digital marketing and customer acquisition programs, we continue to retain and grow our base of loyal customers. In the third quarter, we had almost 1.4 million more identified households versus the prior year, allowing us to better personalize the customer experience with relevant offers and communications. The more customers engage with us, the more they spend. For example, our Just for U shoppers spent $8 to $10 more per week than other customers. Similarly, in-store customers increased spend with us by an average of 28% when they also use our eCommerce offerings.
These growth objectives will be enabled by enhancements in 3 areas. The first is productivity. We have identified a number of initiatives to fund strategic growth investments, offset cost inflation and support earnings growth. These include taking better advantage of our scale in purchasing, working with our vendors to create winning partnerships, improving shrink in our stores and improving labor efficiency across the entire company.
The second is technology. We're investing in a modern cloud-based infrastructure, digitalizing core capabilities and investing in automation in every corner of our business. Technology will underpin our growth and productivity agenda.
The third is talent and culture. We're adding to our talent pool and putting our leaders for the future in key positions. We recently hired Chris Rupp as EVP and Chief Customer and Digital Officer. Chris joined us from Microsoft, where she most recently served as General Manager of the company's Xbox Business Engineering team. Chris also spent 11 years at Amazon and was Vice President of Prime before she joined Microsoft. She will be responsible for integrating and enhancing our customers' experiences across all our digital touch points, accelerating our eCommerce business and deepening our customer relationships through our loyalty programs. She will also assume responsibility for our enterprise data model and data science capabilities.
We continue to focus on our front line, making every day a better day for our people and our communities. For instance, we continue the education of future leaders through our Albertsons University program with 97 attendees in 2019. And separately, through an extensive online program, we trained more than 225,000 employees on diversity and inclusion. In addition, we've donated more than $226 million in value to food banks and other hunger relief agencies and supported 2,000 organizations in our communities through foundation grants.
Now I will ask Bob to cover our third quarter results.
