Just always was amazed at the different prices an item sells for. For instance there will be bidding on an item up to $50.00 but same item will be BIN$35.00! Shipping is the same and the feedback looks good but people rather bid then BIN? I noticed this while I had Boots serum up for auction. I started bid at $25, saw people were bidding LOTS, one even sold for $137 but mine ended with no bids. While I relisted it, it sold for $42. This was a good price but compared w/$137. Also, there were plenty of BINs for around $50. I guess people rather bid. I know its a timing thing too. Items sell better ending at night than say afternoon?
