Walmart Ad match. Still trying to figure it all out. I'm not too sure how many coupons I can use all together along with the ads?
You can use an ad match plus a mfr coupon plus a Walmart coupon on each item. Check the top of the coupon, it will say manufacturer coupon. If the Walmart coupon is truly their own and not just a mfr coupon they supplied you can stack it (use together).
Also if you go to savingscentral.walmart.com (pretty sure that's the URL) and enter the code from your receipt they will automatically credit you any ad matches you missed! You get an ecard. I love it bc my store hates to match razor prices and always finds an excuse. This site does it no problem ;)
