I love this method! I will try flea markets too! You can look at items see what they are going for on eBay and see if it's a good buy. A month ago I found a McDonald's/Coca-Cola baseball from a company operations meeting in 2000 in its packaging. Looked it up saw they were going from $50-$125 and I asked the vendor how much he said $3! I'll take it. Sold it on eBay for $75.
