Now, I'm at the phase of "do I really need this cluttering my life"? My answer is usually "no". Save my shekels for those things which are expensive and I really DO want which I can either use as an investment or deduction. Small ticket items to accentuate, in between those big purchases.
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 :)
