When buying from a mystery seller, you will be subjecting yourself to risks like unsent merchandise, items that do not go with their particular posted description, bad post sales help, or misuse of your credit card details.  Researching the sales past of the dealer will allow you to identify if the vendor is reliable or not. A lot of major nationwide brands with an authorized internet site are reliable, therefore it is recommended that you check out the standing of an unheard of business or label prior to ordering anything from them.
