It has to be said, I agree with the 'point of sale temptation' thing.
I'm a fiend for impulse buying, and I also like my 'boys toys' (and talking of cars, I've just taken my 405bhp Cosworth off the road for winter storage - and you're right about 16 year olds - they practically have to cold shower when I drive by, especially with the 3.5" straight-through pipe gurgling away and the whoosh of the dump valve ripping their ears out...)
Sorry, but I miss it... back to the practicalities of the Range Rover for 6 months
Anyway, this whole 'temptation/desire' buying thing is exactly why I think that retail stores and high street shops will always win over online selling... sure, online retailing is cheaper, quicker and more convenient - but the thrill of walking into a magic shop and seeing something being demoed and thinking 'I want that!' is a feeling you can't emulate online.
Same with supermarkets, clothes shops, retail stores etc.
And as far as overrated being confused with overhyped, they really are one and the same. Far too many other online magic resources 'hype' things before they're even available. That's called pre-marketing. You can get a feel for the market before an item even hits the shelves.
The other thing to add is that overrating can consist of a few variables: Chinese whispers, marketing bullshite, ignorance, dishonest advertising, heresay, plugging, the list goes on.
When selecting an item for that special purpose, it's always good to buy on either experience or recommendation - not hype.
The old phrase used when I was training as a designer was 'If it doesn't look good, it isn't'... and with magic - I believe that to be also true.
And to say that magic is a business is true to an extent - but much magic is actually LEARNED or HANDED DOWN - it's only the quick-fix gimmicks and stage illusions which are inherently dear - and the prices are justified by the manufacturers having the monopoly over the rest of the market, because they hold not only the keys to the design/method, but also the performance rights.
Personally, I am duped all the time. I am easily drawn in - hook, line and sinker. And I spend money like water on things that make me happy. Guilty as charged.
And yes, I frequently buy things which I then discover are overrated - but, that's the danger of the fast-paced, hyper-retail, mock-marketing capitalist society we live in.
And the problem is, sometimes, just by buying an 'overrated' item, you can perpetuate it's popularity.
Hmmm... feel cheated, now!
