    About Our Prices

    We strive to provide you with the lowest prices possible on Walmart.com as well as in our stores. However, sometimes a price online does not match the price in a store. Walmart.com's prices may be either higher or lower than local store prices. Prices may also vary between stores. Our local stores do not honor Walmart.com pricing or competitor advertisements from outside of a store's local trade territory.
