You know, Its funny because I was so angry when I had to fight with a cashier the other day at walmart about the whole one per purchase/transaction difference but now I can totally see where these poor cashiers are coming from. They've probably accepted fake coupons in the past or been tricked by dishonest couponers and have gotten in trouble. As for stores setting limits its people like the women I ran into that are to blame, I wish I knew what happened after they went to customer service.
