I've switched to other independent online shops as I can usually find what I want. I just search for "buy 'something' uk" on duckduckgo and can always find a few good non-Amazon sellers.

I avoid Amazon as much as possible now since it's no longer possible to rely on their reviews and there are way too many results to be able to find one that's not fake or of extremely poor quality.

I'm starting to appreciate going to brick-and-mortar shops again and having the choice between only a dozen of good quality products, instead of thousands cheap barely usable ones.
