Do you think its sad shopping at thrift/used clothes stores?

I shop at those stores, not because I have to, but because 1) the money goes to a good cause and 2) why the hell would I choose to spend all of my hard-earned money on clothes when you can get items with the tags still on them for up to 90% off retail? Sure, I could afford more expensive clothes, but I'd rather save my money for things like vacations, a house, gas money, etc etc etc.
