Im currently in negotiations for a trade of about 90 NES manuals with someone on Ebay. For 13 of those Im going to trade manual to manual. However, the other stuff involved is boxes, foam blocks from the boxes, dust sleeves and some games. He said 1.5 manuals per box, 1 manual for 5 styro blocks, and 1 manual for 4 dust sleeves. I can figure out what I want for the games, but what do you think about the trade rate for the boxes, styro, and sleeves? I was thinking this is more or less fair although 1 manual for 4 styros may be better. Nothing is extremely valuable - think lot value. Thanks
