I am the same as you. Although the only difference is:

1. Amazon is the never the cheapest. 2. Their search is absolutely garbage and I can't use it. I'd need to go elsewhere, find a specific product, then search to compare.

I just logged into Amazon and the last thing I bought was 2021 "Leuko Tape" for hiking since it was the only seller that had it at a reasonable price.

I am genuinely always amazed by the responses on HackerNews. It might be because amazon.com is just cheaper in general than amazon.co.uk?
