We only get 30 free listings a month
but our final value fee is 7.9%.
I used them on some stamps last month plus other things around the place (son's Thomas the Tank Engine stuff went well!!)
I was going to do thirty auctions a month until all the stuff is gone. I figure the things aren't getting used and they aren't worth anything to me sitting on the shelf so it's better to get money in the bank for them. I started with a pretty minimal price.
I did offer free postage on second items which I think helped people make bids on subsequent auctions.
I do wonder at some of the proces people start with - used sets at retty much the original value seems to be just grasping at straws.
