And, usually, I shrug those coupons off because they are $.60 off of a product I wasn't going to buy in the first place, so I don't care. On the other hand, if I buy something at Bed, Bath and Beyond or almost any clothing retailer without a 20% off coupon, I do indeed feel like a chump. If the cashier in a store I've never been in before asks 'do you have any coupons?' after ringing me up, I definetly feel like I've screwed up, but I'll still finish my purchase because, well, instant gratification and societal expectations and all that. But I'm not going to go back to that store until I DO have coupon. So maybe it depends. If your shtick is 'Never pay full price and find ridiculous discounts,' coupon fields might be the way to go, as long as you always have coupons available. But if you expect even some customers to pay full price, having your cashiers ask everyone for coupons is probably not the best practice.
