I always get the impression Amazon doesn't care about customers until they complain, and then they are suddenly very nice. Why not add some obvious QA features like: - reporting fake reviews - reporting fake/misleading listings - reporting fake reviewers - reporting listings where the product has been changed for something else Many other glaringly obvious issues: - vastly different products listed on the same page (to gather more reviews & sales = better ranking) - shipping cost > item cost - sellers promising a refund for a good review (especially to those that complain) - fake 'only 1 left in stock' listings - always-on-sale listings - ... Also while I'm complaining, as a frequent Amazon shopper there are a few missing filter/search options, in particular: - listing age - not deliverable to your address/country (frequent issue I have with cross-border shopping)
