Amazon was built on trust. I bought a book from them in the early days. It didn’t arrive after 2 weeks and they said ‘we believe you’ and they shipped me the book again at no charge. A week later i got 2 books, the first was lost in transit. Contacted amazon and they and no problem keep both and give one to a friend. I and many others were loyal to amazon after these experiences, paying more due to the lack of hassle and high trust. They became the default online bookstore thanks to this trust. It wasn’t even worth price comparisons, you looked on amazon and bought it there knowing you’d get the product you paid for.
That’s now gone. They have fallen to ebay levels of trust at this point. You’re likely to be shipped a box of rocks rather than what you wanted at this point.
People are willing to pay more for trust and the lack of hassle it represents. I want to buy a hard cover book that’s well printed. If i keep getting poor photocopies on tissue paper the trust is gone. I'll happy pay more to buy from a site where that never happens. I won’t even bother with price shopping when one site is a good chance of a scam and the other isn’t. In fact i’m pretty sure that’s where amazons dominance as the default online store came from and i’m shocked at how little care they have for this fact.
