So I don't know if ya'll have heard about the Walmart Savings Catcher but I have and I downloaded it. I went to Walmart the other day, uploaded the information from my receipt. If they find any item sold at another retailer for a cheaper price, they will refund the money in the form of a e gift card. I have no idea if I will get a refund. It can take up to 72 hours to find out. This could be really helpful if you shop in Walmart.
