I have heard of several people taking the Albertsons ad into Wal-Mart and price matching the Del Monte Vegetables for $0.49 AND using the $2.00 off 10 coupon that is found in the ad on top of the price match.
I want to point out that you should NOT do this. The price in Albertsons' ad clearly states that the $0.49 price is AFTER COUPON.
I know that a lot of cashiers won't read the fine print in the ads, and will probably price match the item for you, but I strongly encourage you to be honest when price matching.
When people start abusing coupons/price matching it just makes it so much more difficult for everyone else, so PLEASE use your coupons and price matching ethically.
