I believe in investing in quality products that will last. Not just trivial beauty products, but anything; if I buy a coat, I don’t want to have to replace it in at least five years. My time is worth a lot to me; I don’t relish having to spend my time to replace things when I could spend a bit more and have it last. Then, net-of-the-net is that I’ve spent less time AND money on that particular purchase.
In short, I’m comfortable with higher up-front investments (within reason, of course – price does not equal quality). Some believe the Dyson Supersonic hair dryer is just that.
