Proxibid should NOT be trusted! Their sellers sell items that are misrepresented. Many items are consigned and they have no idea what their selling. For instance; some may say it's sterling when it's not. Some items may sa "rare", but it's just an adjective to get the buyers to bid.
Also, the software goes to the highest bidder and it's not in increments.
