It's a growing problem with Amazon that for whatever reason isn't being addressed.
Issues like this are probably due to Amazon's size and culture, which competitors could take advantage of.
Anther example of Amazon doing an unexpectedly poor job was when my brand new seller account was rejected/disabled by mistake, it took significant effort to get any human to look at my case.
Yeah no, if you go into a normal brick and mortar store you can be pretty sure that what you're getting is not counterfeit. Stores are still not competitive with Amazon.
Anecdotally, it's enough to nudge me into alternatives. Other people are saying they know people who decline Walmart shopping for similar reasons but on the other hand with about half of US households using Amazon Prime it's a drop in the bucket.
