Shopping Woes

Why is it that every time I have no money I always find lots of bargains while shopping? Today I went to an outlet mall in Georgia and found so many great deals, but of course I'm not supposed to spend any money this week. Anytime I have a couple extra bucks and go shopping, there is nothing within 100 miles that looks at all pretty. Why is it like this? Does anyone else have this problem? What can be done?
