Farmers market on steroids!

[FitoPharmer]

I had a question or two because I was very excited when you first posted this. But then I read:
"The auction fees are as follows; $1-$100 16.75% $101-$300 15.00% $301-$1000 10.00% $1001-$10k 4.75% Free to list! Free to re list! $0.50 To highlight $0.50 To Bold $1.00 Buy it now"
I was just wondering why the fees are so large? especially when frags.org, Canreef, Ect. offers a similar service with not as many features but for 100% free. I mean don't get me wrong I wanted to post some stuff on your auction site, but if you make $16.75 off my single 100$ sale, that's like making pay pal fees seem cheap. And i would rather pocket the 10$ after Pay pal and post my own auction. For me Pay pal offers excellent functionality and security for only 3-5% per transaction.

Has anyone from the public used the auction service yet? The only listed vendors seem to be retailers. And I was also wondering what justifies such a high charge rate? Is it to cover the cost of the small things people might sell, like 5$ frags? Or is there more cost to hosting this service then I imagine?
