I was just asking this to myself today when browsing safety-razor blades on Amazon. (I was not able to buy them directly from the manufacturer’s website.) When I tried to start filtering by who sells it, I just got a bunch of names that meant nothing. I eventually bought them on Walmart’s site because, I guess I trust it more? Some of the comments on Amazon had the dreaded “this has changed recently,” and the last thing I want to do is scrape my face with counterfeit razor blades.
