I went today and bought several things ~ but not too many. One of the items I bought was Kraft Big Slice Cheese. I bought 4 and had 4 $1/1 coupons. The first 2 scanned fine. The next 2 would not work. The cashier made them work after lots of trying.

I only had a few other coupons and they all worked fine.

Why did this happen? I hate having people behind me rolling their eyes because it takes so long to check out.

Thanks to anyone who can help me understand why the Q's wouldn't go through as I hoped.
