When I need a 'shopping fix'....I go to the Goodwill 2 blocks from work....
I can spend $5 and come out with bags of books, kithcen gadgets, crafts stuff and just fun stuff.
And I don't feel guilty if in a month, I bring it back :)
As a matter of fact, a couple of the very well to do from a City near mine, appeared in my particular Salvation Army one day. We waved at each other from a distance, almost a wink, 'cuz they'd caught me coming out of their local "2nd hand place" the month before.
A bargain's a bargain -- doesn't matter what income class you are in.
