I have successfully almost completely cut Amazon shopping out. We would spend hundred of £s every month and would buy everything off Amazon. But the company is terrible (mistreating workers, avoiding tax, etc etc). They’ve allowed their site to get flooded with removed trash. Reviews are unreliable. Prices are comparable or more expensive to elsewhere. I do still buy from there once in a while for quick delivery and easy returns.
Alternatives:
eBay - sucks for product reviews, but is good if you know what you’re getting (e.g. something branded). Delivery is through the post rather than mistreated delivery drivers needing to piss in bottles. I managed to help a hospice by buying excess stock it had via eBay.
HotUKDeals - a sales sharing website that links through to other small retailers with good bargains. I find stuff here frequently and always search this site first when I want something.
Overall I’m buying a lot less stuff and I’m really happy with that.
