How do I do a price match at Walmart?

What is a “price match”?
A price match is when you find an item that is within the allotted guidelines (HERE) and ask the cashier to “match” the price of a competitor. 

Walmart does offer price matching under the following circumstances:

• We do honor “Preferred Shopping Card” advertised prices. Must be like items, be advertised and require a competitor’s shopping card, for the discount to apply.
• We do not honor advertisements that require a purchase in order to receive the advertised price or free product.
• We do not honor “Buy One / Get One Free” advertisements.
• We do not honor double or triple coupons or percent off advertisements.
• We do not honor other retailers’ “Misprinted” advertised prices.
• We do not honor Internet Pricing.
• We do not honor competitor advertisements from outside of the store’s or Club’s local trade territory.
• We do not require customers to have the ad with them to honor a competitor’s ad.
• Items purchased must be identical to the ad (size, quantity, brand, flavor, color, etc.)
