Complaint / review text:
Vendor processes order automatically with shopping cart connected to coinjar.com bitcoin processor. Cart doesn't work well. When he receives complains, he says it is buyer's fault, and go get the money at coinjar.com as the merchant has the money not him. Coinjar.com tells you to contact the vendor. Result: you waste time and money.
Scammer - even though he's mentioned in many tutorials on dark web, stay away
