We've begun ebaying more. Also Craigslist; the plus to CL is there are no fees. The big plus for Ebay is you're reaching a global market. I have done well shopping seasonal clearances at Wal-Mart and Target; both will sell things for pennies on the dollar when the season shifts. One example is some ice auger blades I purchased last spring for $9 a set, and just sold for $20 a set on E-bay. They are an item that normally sells for $40, so I had no problem selling them for $20 and seeing a nice profit. Golf balls usually go on sale when winter hits, and they can be good sellers.
I just purchased a case of Polaroid film, for $7 a box, and the Ebay price is $15-30 a box, depending on the condition. Shipping is really cheap as its a small item, and that helps with the sale.
