Go to Ebay and do a search of "completed items" and see if your videos are selling and how much they are selling for. Then try selling at the yard sale for around that price..... if you don't get your price at the yard sale then hold onto them and Ebay them after. I personally would be willing to take to bit less than Ebay price at a yard sale to avoid the hassle/fees associated with Ebaying. But I certainly wouldn't take a LOT less................P
