One of the blogs I read every day is Give Me Back My Five Bucks, which is written by a young Canadian girl who paid off all her debt and is living a wonderful debt-free life. She posted this list of how much money she would spend on certain things: http://www.krystalatwork.com/2009/10/what-are-you-comfortable-spending.html
I found her list facsinating and thought I'd post my own list...but I'm adding what I usually spend as well as my limit:
Purse: $10 - $80
Wallet: $5 - $35
Winter jacket: $85 - same
A pair of knee-high boots: $50 - $80
A casual but not formal dress: $30 - $60
Formal dress: can't even imagine buying such a thing but I guess I'd spend $150 if I had too.
Pants (inc. jeans): $35 - $60
Computer: $1,500 - 3,000
Sneaks: $25 - $150
My limits are quite a bit lower than Krystal's but I think that is at least partly because I buy a lot of stuff at thrift stores and so pay much less. I went for years never paying more than $8 for jeans because I always found perfect jeans at the Salvation Army store near my office. I also have gotten purses for years and years at KMart for $10, but this year I found a darling purse I had to have at Filene's basement downtown. It cost $80 which almost choked me and will prolly horrify Sheldon, but I have loved it each and every day and I get compliments on it all the time.
I found this to be a very interesting exercise...you should try it!
