I think you fundamentally fail to understand how economic consumer choice works.
The fact of the matter is that the "cost of production" is almost totally irrelevant in consumer choices.
Say, for instance, you were dying of a disease that could be cured instantly by a certain pill. That pill retails for $100, but in actual fact the materials and labor that went into manufacturing it cost only $0.10.
Would you really feel you were being "ripped off" by the drug maker? That his one million percent profit was somehow obscene or immoral?
Or would you, instead, focus on the fact that the amount you paid ($100) was FAR, FAR LESS than the value you put on your continued existence on this mortal plane (infintite, or at least a lot more than a hundred bucks..)
Conversely, think of a luxury house built adjacent to the Chernobyl nuclear reactor. That house COST a couple of million dollars to build (its got marble bathrooms and granite countertops in the kitchen.) Do you think you are getting a good deal if you can buy it for "only" $1 million? That the seller is doing you a service by letting you buy it for a low price?
Its the same thing with Accessories, or indeed virtually any good or service. Consumers will pay what they feel the product is worth it to THEM.
All a bit facetious for this thread, just enjoy your product and stop giving people lectures on what they should or shouldn't be buying!
