Those women sound rather pathetic. When my husband was in college, he worked retail and he told me about how some women would just shop for fun and then return everything the next day. So, they feel like they are getting all this stuff with no intention of keeping it ever and return it the next day and go shopping again.
Personally, it's people like this who drive prices up. Some people just do not have any class.
I hate returning things because I feel like it's wrong of me to do so, if I was so unsure, I probably shouldn't had bought it in the first place but when you're talking about $2000 for a purse, I feel differently about it. I also don't think you should wait months before returning it either. Give the store a chance to sell it in that season. A day or two won't matter... couple months will.
Anyways, my two cents!
