My problem with this topic is that I don't even really know what that is. I go for value for money. If a certain product does what I want better than cheaper options, then I might pay more for it but that's not always the case.
I once splashed out and bought a whole heap of Clarins products which cost me quite a bit of money. I'd much rather spend my money elsewhere. So now, whenever I need a new product I'll do a bit of research first and decide which product will do what I want for the least amount of money. Of course, sometimes this doesn't work out amazingly. But then, you just try a different product until you find one that you think is perfect for you.
It's the same with clothes. I like to buy clothes that suit me. I'm not worried about brand or anything like that. I'm just worried about if it suits me and what quality it is. Sometimes with clothing, it does mean spending a bit more than you would on cheap clothes from, say, The Warehouse, but it will last longer.
So, all in all, I think it all depends on what YOU want from a product. I just want to be happy, and save money for things I really want (like a holiday).
