Well, sure--I mean, what do people imagine? The manufacturer would gladly put your name on them, too, if you'd just buy 100 or more, pay cash up front, and not try to return any for reasons of poor quality control.
I suppose it's an open secret that some people organize private "group buys" from these same manufacturers. For a lark, I was in on one that very nearly went through this past year, but fell apart at the last minute; the same Chinese-made stereo ribbon microphone that is widely sold for $600 under a semi-respectable brand name was going to cost us each around $230, shipping included.
You may think that these microphones are quite a bargain, in other words--but you ain't seen nothin' until you realize what kind of bargain they must be for the dozens of companies who are selling them to you with their name on them.
