I received a $1/1 Heinz Vinegar coupon in my SmartSource insert yesterday. I hear this was a regional coupon, so hopefully you got it too. If so, you can pick up free bottles at Walmart (and possibly Target too!) This product is priced at $1 at most Walmart stores, plus the Target price ranges from about $1-$1.12. Your scenario at either store will look something like this:
BUY ONE HEINZ VINEGAR, regular price $1-$1.12
Use one $1/1 Heinz Vinegar coupon, 6/24 SS newspaper insert
NET PRICE: FREE to $0.12, depending on local pricing
