The price difference is partly due to people selling Razrwires which they don't like, partly due to the things not selling well at Oakley's price (it's too high!) and so lots being returned by stores and sold off cheaply and partly due to the Razrwires being particularly targeted by fake makers because people think that there's no way you can get fake Razrwires (I used to think that...)

also coz motorola dealers can get it from motorola for much much cheaper than from oakley.

I think the low price is mostly because people don't want them...

case in point, the bulk u see that big sellers are selling cheap is coz they get cheap.
case in point, i got mine from motorola and got it way cheaper than if i had gotten it from oakley.
just sayin from experience. and yes i also know some online sellers are also motorola dealers so just sayin y they can sell cheap.
-----
motorola was in the red recently, or still is, so i think they selling some of their stuff way way cheap to dealers was to get some liquid back and not have assets tied up in unsold goods

edit:
oh wait.. yes youre also right.
law of supply and demand. oakley and motorola have too much supply... ud be staggered at how much motorola shaved off the price for dealers (dont let anyone know i said this.. shh) ....

Razrwires are underrated(IMO) and I'm surprised they haven't taken off in a bigger way. I guess not everyone is impressed with the styling and there's loads of other Bluetooth handsfree options out there too. Hopefully Oakley will address some of these(styling) issues and offer more functionality(like stereo Bluetooth) etc. in the next version.

Right now I'm in urgent need of a Razrwire Module(just the module) in Mercury Silver and thus far have had no luck sourcing one. I'd look to eBay(where they do pop up every now and then) but there's so many FAKES on there now that I just don't wanna risk it. If anyone can help me out.. pls do PM and let me know.
