You just never know. I had an item listed on eBay for fixed price for 30 days. The price? $1.99. I had several lookers, some watchers, but nobody purchased. I finally got around to relisting it last weekend, but picked a 7-day auction instead. I started it at the same price, and whaddaya know? It doesn't end until tomorrow and it's currently bid over $5!

It's all about timing, I suppose, and buyer psychology. Maybe the $1.99 fixed price scared people away that it wasn't the "real" thing. It was a rock bottom price and I would have only earned half that in profit, since my shipping fee is always actual or maybe just 25 cents more for supplies. But I just was tired of hanging onto it and I'll never use it. So, maybe at a fixed price, they thought "no way, something is wrong with it". But, with an auction, people figure things that are worth hundreds or thousands sometimes start at 99 cents, so it's okay.

I'll never know, but I'm glad it will sell!
