I try to find something when I'm on a organized shop hop or Row by Row. I usually have a project in mind and am looking for something specific so if they don't have it I don't feel guilty. I do think that shoppers should at least look around the store and spend some time if they are on an organized shop hop or Row by Row rather than just picking up a free pattern or getting your passport stamped. The purpose of these events is to get you to come to the store and it's nicer if you at least look and see what they have to offer.
