Buy nothing new for a month??

I've decided to try the "buy nothing new for a year" thing....but only for a month. I thought I'd give it a try...and try it month by month on a trial basis. Maybe I'll make it 2 months, maybe I'll make it a year.

I walked into Target to return a bunch of shirts and random crap I had bought last week while my husband was away. I realized that I didn't need these things and that the money was better off in my account. I realized that while I give my husband a hard time for spending money on large ticket items...I do a lot of frivolous spending of my own.

At the end of the 4 weeks I'm going to compare my bank statements and see what a dent my "latte, target, pottery barn, gap, old navy, jamba juice, eating out, ebay, etsy-factor" has on our pocketbooks. I'll probably want to curl up into a ball with nausea when I see it....but it will be a good reality check.

Tell me, have any of you ever tried anything like this before?
