Shaving foam: its so much worse for the environment and always with horrible perfume. Shaving soap is amazing, like in the old days.
Safety razors: the old one-blade ones are sometimes more of an investment (10-15โฌ) but the blades are way cheaper and standardized. You never need to buy overpriced stuff again.
Agree on Soap. All the fluid stuff with perfume is money waste.
New tech. Wait 2 years and get some used ones for โ the price.
Clothes: there are cheap quality brands, but expensive ones are often made in the same factories. Nike, Adidas, Gucci, LV, ...
Toilet paper: simply buy recycled. Its the last process of paper recycling (lol) so why?? Why would you buy brands that have weird contracts with logging companies and destroy forests?
Conventional Food brands doing fruit Joghurt, dairy products, meat, with only fake seals. Its literally the same bullshit in there. Same for Crisps, ...
Flour, sugar, electricity, coffe, ... they are all different cathegories. If you buy ecological, full-grain etc. they have different growing standards, so its a huge difference.
Often its about investing more one time, and then keeping it. Capitalism prevents that, as it doesnt make much sense for companies today, to survive.
