My daughter and I were shopping at an Express store . We had 2 coupons-one for $30 off $70 and the other for $40 off $100. In trying to find the best combination to use for the coupons the salesgirl fist rang up 2 items for around $80 and used the $30 coupon where the total came to $49.60. We decided that the $40 off $100 was better so we returned the 2 items for $49.60 and bought everything else and after using the coupon the total came to $62.00.I remember it well that when the cashier rang up 4 items the total came to $94 and she directed my daughter to the clearance jewellery rack where she picked up a necklace, which she didn't need, for the total to reach $102.00. Then the $40 dollar coupon was applied and the total came to $62. When my bill came in the mail I saw that I had been charged for both $49.60 and $62.00. The return for $49.60 had not shown up in the bill. I went back to the store to try and resolve it there but they kept insisting that I was wrong. One of them kept rolling her eyes at me, looking and showing her exasperation. I know I am right and that the store has charged me twice for the same items. I wrote to corporate and spoke with 2 people. They were no help and kept insisting that the receipt total without the coupon adds up to $150 and I have been trying to tell them that if that was the case then why did the salesgirl tell us that we are short of $100 by 6 dollars. $100 was the total needed to get the $40 dollar discount.
