sales mix. Certain of our initiatives are intended to address this sales mix trend; however, there can be no assurances that these efforts will be successful.
As we work to provide everyday low prices and meet our customers’ affordability needs, we remain focused on enhancing our margins through inventory shrink and damage reduction initiatives, as well as pricing and markdown optimization, effective category management and inventory reduction efforts, distribution and transportation efficiencies, private brands penetration and global sourcing. Several of our strategic and other sales-driving initiatives are also designed to capture growth opportunities and are discussed in more detail below.
We continue to experience significant levels of inventory shrink. Although we continue to take actions designed to reduce shrink, including refinement of our self-checkout strategy, and believe these actions are starting to positively impact the trend, we anticipate shrink will nonetheless materially pressure our fiscal 2024 full-year financial results.
We continue to implement and invest in certain strategic initiatives that we believe will help drive profitable sales growth with both new and existing customers and capture long-term growth opportunities. Such opportunities include providing our customers with a variety of shopping access points and even greater value and convenience by leveraging and developing digital tools and technology, such as our Dollar General app, which contains a variety of tools to enhance the in-store shopping experience. Additionally, our partnership with a third-party delivery service is available in the majority of our stores, and we continue to grow our DG Media Network, which is our platform for connecting brand partners with our customers to drive even greater value for each.
Further, we continue to evaluate and evolve the pOpshelf concept, in light of the softer discretionary sales environment, and have continued to convert certain pOpshelf stores to Dollar General stores. pOpshelf is a unique retail concept focused on categories such as seasonal and home décor, health and beauty, home cleaning supplies, and party and entertainment goods. At the end of the second quarter of 2024, we operated 229 standalone pOpshelf stores.
Our “DG Fresh” initiative, a self-distribution model for frozen and refrigerated products that is designed to reduce product costs, enhance item assortment, improve our in-stock position, and enhance sales, has positively contributed to our sales and gross margin performance since we completed the initial rollout in 2021. Moving forward, we plan to focus on additional optimization of the distribution footprint and product assortment within DG Fresh with the goal to further drive profitable sales growth.
We also remain focused on capturing growth opportunities. In the second quarter of 2024, we opened a total of 213 new stores, remodeled 478 stores, and relocated 25 stores. In fiscal 2024 we plan to open approximately 730 new stores (including any pOpshelf stores or stores in Mexico), remodel approximately 1,620 stores, and relocate approximately 85 stores.
We expect store format innovation to allow us to capture additional growth opportunities within our existing markets as we continue to utilize the most productive of our various Dollar General store formats based on the specific market opportunity. We are using two larger format stores (approximately 8,500 square feet and 9,500 square feet, respectively), and consistent with 2023, expect the 8,500 square foot format, along with our existing Dollar General Plus format of a similar size, to continue as our base prototypes for the majority of new stores in 2024. The larger formats allow for expanded high-capacity-cooler counts, an extended queue line, and a broader product assortment, including an enhanced non-consumable offering, a larger health and beauty section, and produce in select stores.
We have established a position as a low-cost operator, always seeking ways to reduce or control costs that do not affect our customers’ shopping experiences. We plan to continue enhancing this position over time while employing ongoing cost discipline to reduce certain expenses as a percentage of sales. Nonetheless, we seek to maintain flexibility to invest in the business as necessary to enhance our long-term competitiveness and profitability. From time to time, our strategic initiatives, including without limitation those discussed above, have required and may continue to require us to incur upfront expenses for which there may not be an immediate return in terms of sales or enhanced profitability.
Certain of our operating expenses, such as wage rates and occupancy costs, have continued to increase in recent years, due primarily to market forces such as labor availability, increases in minimum wage rates and increases in property rents and interest rates. Significant or rapid increases to federal, and further increases to state or local, minimum wage rates or salary levels could significantly adversely affect our earnings if we are not able to otherwise offset these increased labor costs elsewhere in our business. Furthermore, in April 2024 the U.S. Department of Labor announced a
