Interesting thread and article.
If a high end brand is allowing TK Maxx to use their label against a lower quality product then they risk damaging the sales of a full priced product in other high street shops.
If you by a brand xyz product from TK Maxx and it doesn’t last very long how likely are you to buy another of their products full price?
Not sure if it’s the case now, but a few years ago electrical appliance manufacturers would have model specific for high street store like Currys. Last time I bought a TV most of the Samsung’s were specific models for Currys, which you’d never find on the Samsung website.
