Amazon used to be the place I went to learn about the quality of a product. If it looked good, well, here I was already on the product page...
Now, with the counterfeit product problem I will no longer consider amazing for anything health, safety or food related.
With the fake review problem, I no longer look at Amazon to figure out if a product is quality or not. Which leads to more purchases from physical stores or other websites.
Between the two of those issues, my use of Amazon has dropped pretty significantly (to the point that I cancelled Amazon Prime during the pandemic).
