I ordered what was claimed to be a factory repair manual for my car. I received an incomplete, out of order, and nearly illegible copy of an aftermarket manual. I was surprised because the feedback on the page indicated that the manual was the real factory manual. I left negative feedback, only to find it was being changed by the seller. Tradebit did refund my money, but they have yet to change their feedback system. So long as sellers can alter the feedback, I don't think you can trust that you will get what is advertised on Tradebit.
