I was on there this week to look at my previous orders from years ago and find certain items that I knew I had bought some of but seemed to have misplaced. turns out my last order was over 6 months ago, which surprised me — I thought I had ordered more recently for high priority projects where I needed something the next day.
I was also on there for a similar reason looking for some car parts because I wanted to get something done last weekend, but ended up just ordering from somewhere else and substituting a part or two.
but yeah the quality is probably the most effective turn off? like in the past couple years there's definitely been a few scenarios where I thought "oh yeah Amazon would have something for this", and only used that to find the key search terms I should be using elsewhere, because you just know that whatever you buy off Amazon is going to be garbage
