You pay for more, you get more, but that's nothing to do with 'Premium Brands" - You'd expect to pay more for 2 kilos of tomatoes than 1.
I'm sure you disagree with me, but that doesn't mean you're getting value for money.
I don't WANT aftersales for shoes, I want to buy them and wear them and never have to think about them. The materials? What are they made of? Unicorn leather with linings from the ear of a Dodo? They're cow leather probably, really it can't be THAT different...
I want shoes to be comfortable and value for money - I've had 'better' shoes that weren't comfortable and gone back to buying cheaper shoes that I can wear all day... I also NEVER wear leather soled shoes as they're like walking on ice on slippy tarmac...
I don't think you've made a case for that being anything other than your preference.
There's nothing at all wrong with liking a brand, be it Rolex or Boss (I keep saying I'm going to buy a Boss suit, because I think they're nicely cut, but I rarely wear a suit and have 5 in the wardrobe already!). Aldi - I wouldn't shop there personally - I've been in a few and they're bloody horrible places for the small difference in price, in my view.
Spending hundreds on shoes and thousands on watches but buying no-name brand food for a few pence less than something they've been enjoying for years seems to be a case of having priorities a little skewed.
Fuel is NEARLY all the same, but I won't put Tesco petrol in my Mazda (no 'premium' brand for me ) as when I have, it's run like a dog... As it's, at best, 1p less than Esso and BP in our local garages, no problem.
Tyres seem a place where premium is a bit over-rated, but there is a point at which I'll say "too obscure" - But having driven on Kumhos for a while, I don't really see a need for Michelins on the average car (I do have Bridgestones on my Mazda, but only because it drives better with them, not because I value the brand..).
Maybe I'm missing your point, though?
If you mean, is it worth paying for better quality or more, of course it is, but that's not necessarily got anything to do with "Premium Brands".
