From such providers it is urgently advised against. eBay expressly warns against payments via Western Union, since via this no buyer protection exists. Even the promise of a purchase-price refund in case of complaint helps no further if the goods are not even shipped or a postal address is missing. The uniform use of pictures for all models (e.g. regardless of the plating) is a typical feature of disreputable shops. Even if the depicted original pictures look genuine, one should refrain from such auctions.
