In your state, do buy one get one free items both ring up at half price or does the first item ring up at full price and the second item rings up at $0? If the first item rings up at full price, then they should let you use that coupon. In fact they should just scan the merchandise and then scan the coupon and let the computer figure it out. I can't believe that the cashier became so involved in deciding what was allowed and what was not.
