I noticed that Ebay is not mentioned too much and this is honestly one of my favorite places for buying clothes at a great price. I just picked a pair of men's plaid Nautica shorts for $1.99 that still had the $49.99 tag on them and a pair of men's plaid American Eagle shorts for $2.99 that still had the tag on them (but not the price tag) AND since they came from the same person I paid a flat rate shipping of around $7.00 so I got them both for like $11! They were for my 14 yr old son and he loved them - hs is learning that being in style doesn't have to cost a fortune!
In addition to getting the clothes at great prices, the sellers will often give you the exact measurments of the item so there isn't any guessing when it comes to sizes. This is kind of an added bonus over purchasing directly from a store - see the May Topic of the Month forum on vanity sizing.
I have also begun to collect my children's outgrown clothes and plan to sell them on Ebay as well. I will make more money than if I sold them in a yard sale and it is so much easier! I have been selling my textbooks on half.com (a division of Ebay) and just received my first payment of $184.00 for five books - not what I paid for the textbooks originally but WAY more than the campus bookstore would have given me and much more useful to me than the books sitting on a shelf unused! You can also sell them on Ebay and receive the money yourself which is what I would probably do with any book other than a textbook - people tend to want to buy those immediately without waiting for an auction so I think that they tend to look at places like half or amazon first.
Anyway - that is my budget shopping tip - Ebay - for clothes, shoes, books ... you just never know what you will find. I even purchased a new French door to replace the boring front door on my house - $20.00!
