I've found some fab bargains on ebay too.
To prevent myself from spending too much money, what I usually do is sell some of my unwanted junk first, save up some money in my Paypal account and then use only what's in my account to buy new stuff. That way I never really spend any money...well, that's what I keep telling myself anyway!!
I had a MASSIVE clear out and sold loads of stuff a couple of months ago. There were so many things I thought wouldn't sell but they did!! I bought myself a return ticket to India to meet up with my fiance (he's in the Navy & was stationed over there for a few weeks a while ago) with the money I made!! I just wish I could type quicker so that I wouldn't take SOOOOO long listing every detail!
It's fun but very time consuming-the number of days I've lost to Ebay!!
