Yes there is a influence with the price of fragrances but its usually part of the whole marketing package. The true test would be to test a range of frags blind not knowing who made them then check the price. Then you can measure for yourself if quality means you will be paying more or not.
Its the same kind of thing if you took your girlfriend to a jewellery shop and told her to choose whatever she wanted. She in most cases would go for the most expensive diamond encrusted item. But if you gave her several items of jewellery without the price tag she is gonna go with what she likes rather than the most expensive item.
