On one occasion when I had to return an item I ended up £30 out of pocket because it had to go by courier instead of post, due to length. I had to argue with their customer support to obtain recompense despite it having been them who told me to send it courier. The item was only worth £80.

Nowadays I just use Amazon as a price baseline but shop elsewhere.

On memberships, I don't mind the Prime cancelling issues very much because they seem to always credit back a month if you later tell them you forgot to cancel. Unfortunately, there are annoying dark patterns when signing up, hiding the "No thanks" button when trying to get through an order, etc.

The only thing I noticed is they hide the collection options under a button. By default they encourage you to drop off at a depot or post office.

Now I'm still waiting for a product I ordered 3 months ago. The only option I have is contacting the seller - who doesn't respond. I wrote a review about the experience, which then got promptly removed.

More recently I've ordered a few things from multiple places, the one outstanding delivery is from Amazon, and now almost a week late. It'll probably be the last one; their obvious lack of interest regarding fake reviews, review resetting and obfuscation, misleading pricing, counterfeit products and the constantly shrinking number of quality products have taken a toll. More often than not products are shipped from China, making it a worse choice than many local competitors who may ask higher prices for delivery but at least ship in two days instead of two weeks, have a phone support hotline and a reason to care.

Very slowly but steadily the reasons I started using Amazon's platform eroded away until it became more or less a more approachable middleman for aliexpress dropshippers.
