If you read the satisfaction guarantee you'll see it says "If you see the Satisfaction Guarantee link on an item". We control which items have the satisfaction guarantee - so we will reserve the satisfaction guarantee for sellers that have earned a good reputation with us.
That's clever. eBay never tried this? (I've never bought anything there).
Something else I noticed though is that in the satisfaction guarantee, you mention that you, Bidboxr, will refund the purchase price if it's not what they expected. I see that lasting about two weeks before you run out of money. If you really want to set yourselves apart with a satisfaction guarantee, you may want to look at some sort of escrow service instead.
Just my two cents.
