@pdelcast; don't know if you buy directly from the factory, but some brands have got copycats who copy their transistors/fetts. (without their permission..)
I buy directly from On Semiconductor for my FETs.

What kind of discounts are they giving you? Usually they offer Authorized Distis. and resellers some discounts so we can sell components to EMS, ODM and who ever assembles electronic products. Also, what do you do when there's a shortage or a long lead time on the item you use?
