Price matching at Walmart is common in some circles.
Yes and if you are lucky enough to have a Walmart that has well trained cashiers it can save you a bundle .
Well worth purchasing the Sunday paper and getting all the local adds out , circle the best buys you want and take them with you when you shop.
Walmart doesn't need the sale flyer for price match but having it will save you time . Depending on the area it can even get you better deals (some areas have two different local papers and the Walmart might only have one hand for price matches which could be the one with the least adds)
