It's all fine and dandy until anything goes wrong, such as the seller sending you a completely different item to what was listed.
They will do absolutely nothing about it, and have the audacity to charge you a further fee to dispose of it with zero reimbursement what so ever. They flat out refuse to report the sellers, stating it'll hurt their business (meaning they can't profit from others being scammed). The seller I purchased from relisted the identical item with the same pictures and description days after, with the intention to deceit, and they just shrugged their shoulders.
They've taken their commission and will milk more out of it.
