What was your best reselling experience (something you got free/cheap and resold for $$)?
I love reading about people who have picked up things cheap at garage sales, thrift stores, storage auctions, flea markets, etc and then turned around and sold them for a lot on ebay, craigslist, or wherever.
My best find ever:
I was thrift store shopping a few years back, not looking for anything in particular. As I was browsing the books, I found an old copy of Charlie and the Chocolate Factory and bought it to read to my kids.
Turns out it was a 1st edition. I paid a whopping 25 cents for it. Sold it on ebay a week later for $435 and took the kids to Disneyland instead. :)
What about you? Do you have any great finds to share?
