I made a purchase at JoAnn's yesterday. I had a $5.00 off coupon and a 40% off coupon. The cash register took 40% off my $5.99 item and $5.00 off the $21.99 quilting book that I bought. I thought the amount was more than what it should be a the time that I paid. Should I go back to Joann's with my receipt and get a refund? I was told by a clerk a long time ago that the cash register would automatically decide the best deal when coupons were scanned. Not true now. BTW - All items were regular price.
