Auctions will always rotate to top of list for a short duration. If your start price is low they wiill get views/watcher, that doesn't always convert to sales. If you have a store you can list all year for price of an auction run.

The price you can get at BIN depends on how quick you want to turn it over, and also if you have to wait for right buyer to turn up.eg like it and be the right fit/size.

Unsold high fee auctions have to be paid for from sales of those that do sell
