Those auctions aren't complete. For example, Exotic.ly has 3 bidders and the auction ends in 5 days. It started at $99, but I doubt it will end there. I don't see any "completed" auctions shown... where are you getting that they sell for $99?
EDIT: Found completed listings... on the first 4 pages ONLY 3 ended at $99....

Also, my comment was because you said "as an example Exotic.ly is now selling for $99 -I don't buy .ly or this one I would." But that isn't true - its in auction starting at $99... anyway, I don't want to stray from the BB topic, but found your post misleading and was trying to let others know so they don't waste their time like I did.
Thanks!
