I will say that I used to buy stuff from AMZN all the time and now I hardly ever do.
For me the last straw was when Amazon Prime deliveries stopped arriving in two days despite being claimed to arrive in two. It made a difference because in two days it could be a hassle to drive to the store but in five days I can easily find the time.
Not long after that, Prime service became officially five days at my location while Amazon was shouting to the rooftops that other people were getting one day. Around this time it seemed every other retailer was trying to impress me with fulfillment and often shipping is free if you buy $200 of camera equipment or $80 worth of games, even when it isn't it isn't very expensive but it is always faster than AMZN, I even get Ebay packages from Japan faster than AMZN gets me packages from the next state.
There was also the rising problem that the quality of the listings was going down on AMZN; I'm not so concerned that the $24 product is crowding out the $17 product but rather that there are so many junk products that crowd out good products. On top of that there are many product listings that make no sense at all and it all adds up to a stressful process of sifting through a lot of junk and then not knowing if some absolute garbage is going to show up at my door.
So I went from buying something on AMZN probably several times a week to now less than once a month... I canceled my Prime subscription because I couldn't have any self respect if I was paying a subscription for something that was worse than average as opposed to better than average. And boy is it annoying to shop on AMZN now. The only thing you have to click more times than to cancel AMZN Prime is to order something from AMZN without signing up for a free trial of Prime.
