Silly pricing

When I see a 90% discount on anything I immediately assume the real price is the 10%.

Two things happen when this kind of pricing is used:

1. The perceived value of the item is deroded automatically.
2. If you try to charge anything superior to 10% the client will get mad, storm out of the door (or webpage) and accuse you of trying to rip her off.

So be cautious. There is no turning back once you start using the huge bargain tactic.
