As others have suggested: next door local shops. And then, other online shops.

For example, here in France, the law make it so books are sold at the exact same price everywhere, be it on Amzn or in one of our local bookshops. I’d rather talk to nice human being than fill a web form, and I’d rather do business with someone that can also do business with me than send money to some billionaire. So, I order at the local shop ;)

I find almost everything I need. It just requires me:

• to go there, or to pass a phone call (it’s nice talking to people or to re-learn to do it… and it’s never too late to start doing it either).
• to plan my purchase, as those small shops aren’t open 24/24 and don’t have a bazillion and a half items in stock and they can’t get it overnight either (which is good too as it helps me distinguish between what I need from what I ‘stupidly’ want to buy)

And for the rare few things I can’t get elsewhere (at the very least I will try to directly contact the seller on Amzn), well, either I will have realized I don’t really need them, or I will find some alternative or, then and only then, I will order it on Amzn which since January had not been that frequent, but that’s just me.
