I've always been a walmart shopper. Maybe it has something to do with growing up in Bentonville or maybe I just like saving money!! Since moving to the DFW area Ive really taken advantage of walmarts price match garantee!! I look through all the local ads and circle the things that we use that are a good price. I plan my menu around these things. Walmart now offers a new service called Savings Catcher. You sign up for a walmart.com account and then enter your walmart receipt online. It searches the receipt for any item offered at a competitors store and will give you the difference if it finds a lower price. There are certain things it won't match like produce that has to be weighed, closeout prices, and a few other things. (If walmart paid me to endorse this I would do a better job supplying the information:-)) Check the faq page on the start page for all the rules.
I missed a price match and walmart already creditted me $2!
They do all the work for you! If you are already a walmart shopper I would take advantage of this tool!
