Ah okay, I though it was because these particular tires are in fact made in Germany ;)
But yes I think in Europe small businesses are much more of a thing. In the US it's very hard to get a better deal than from Amazon and these big companies, especially because they can super-optimize the supply chains across such a big country. Same is true in China.
Not to mention maybe another $150 in Uber rides waiting 14 days instead of 1 day for it.
Also Amazon gives me 5% cashback too so that also needs to be factored into all prices.
