First, check this listing and make sure you read all the info (terms of sale, etc)
https://www.bitmit.net/en/item/35806-20-oz-jm-silver-bar-bullionIt is a brand new user essentially asking to not have a transaction escrowed...which BitMit does not allow until you are an established seller.
Furthermore, I happen to know that hand-poured Johnson-Matthey bars go for a premium. ESPECIALLY 20oz ones (a rare size-usually its just 10oz and 100 oz). So, checkout what this SAME EXACT item is going for on eBay:
http://www.ebay.com/sch/i.html?_trksid=p2050601.m570.l1313.TR0.TRC0&_nkw=20oz+johnson-matthey+bar&_sacat=0&_from=R40And the auction is at $200 with one day left?
Would you agree-its time to notify BitMit Admin?
