I can't speak to your hypothetical coat, but this coat is advertised to literally last many years so you are either arguing that it's fine for the seller to lie

I can't speak to your hypothetical coat, but this coat is advertised to literally last many years so you are either arguing that it's fine for the seller to lie or you don't have an argument at all. Also $80 might not be a lot of money to you, but it is a lot of money to most people in this world. So that's not an argument either. I can afford to buy a Lamborghini on impulse, so how come everyone can't afford one, is frankly a ludicrous argument, whether it applies o Lamborghinis or to coats.
