I went to our Target store earlier today and had to get in the line of a checker that did not know how to get the coupons to work. I gave her the info. I read hear about covering up one of the bar codes and she wouldn't listen...it was driving me crazy! She kept saying: "Sorry, looks like you can only use one coupon." All the while there was a woman behind me with her kid in the cart just screaming. She made several loud comments about getting in the wrong line. I kind of wished I could have just snapped my fingers and disappeared.
Anyway, it was definitely worth it in the end because we finally got all the coupons deducted and I saved a ton on money. Lucked out and found some Archer Farms flavored coffee clearanced for $3.28 (used the $1 off coupon), got boxes of Market Pantry saltine crackers for .29/bx (used the $1 off 2 coupon), got 10 boxes of the mac'n'cheese for .10, and last but not least: Hershey kisses (not the ones pictured on the coupon) that were also clearanced for $1.34 ended up being .59 with the .75 off coupon.
We also had a local supermarket (not Target) with chunk light tuna 4/$1.00, and I went and bought some of that as well.
So I've got my food drive bags filled to the top and ready to go on the front porch Saturday morning. Thanks again OP for starting this thread!
