Here's some shit I've bought that lasts:
Cars: 1990s to early 2000s Hondas are forever cars. Basic maintenance, and you can expect to get over 300k miles on the engine. 500k are not an uncommon occurrence. Parts are cheap and abundant. Tangent: some electric cars have easy battery swaps, like the Nissan Leaf. Buy a Leaf for 1k, and a battery for 4k and have a super efficient car that can charge off a wall outlet.
Clothes: Levi's jeans are not as good as they once were but still better than any other jeans. Dickies work clothes last forever and even look ok as they fade. Shoes are mostly disposable today but I've had the same pair of Adidas Superstars for 3 years and while worn, still are functional.
Cooking: Vitamix mixers are a lifetime buy. A trip to the thrift store and buy anything cast iron; plenty of YT vids will show you how to restore. A ceramic kamado smoker/grill will also last forever with only needing simple hardware replaced occasionally.
Miscellaneous: Costco accepts returns on anything that isn't a computer, game console, or TV, regardless when purchased. I don't use this as an excuse to treat major purchases as disposable, but it is an invaluable form of insurance against shit that quite honestly shouldn't break (related: fuck you, Dyson - unreliable, yuppie tech bullshit).
I'm a safety razor user:
Here's what works for me. Shave at least two times. First pass, only use downward strokes. Pass two, upward. If time permits I'll shave up to four times with all the cardinal directions.
Closest shave I've ever had.
