These all sound like you could get them at a sporting store like Decathlon?

I’m not sure there’s a European level online shop that could replace Amazon. In the Netherlands there’s bol.com (individual suppliers but also their own stock), in France you could try maybe from a supermarket like Auchan as it has a pretty large selection.

If your concern is shipping and packing, maybe you can buy some items in bulk, like the sunscreen and vanilla drops? If there is someone in your circle that also uses these things, then you can purchase them together in a single order?

For some reason, at the start, most videos I got recommended in the mobile app were in french.

I guess I need to find some channels I’d want to subscribe to, and go from there

Exactly my dilemma

Even for the government you need apps nowadays. Yes you can try doing things in person but wait times aren’t reasonable. I’ve been trying to get a dumb phone for myself but still find I need a smartphone for specific apps a couple of times a month…
