Ok, I rang Spoiler Shop, and there's good news and bad news ...
Good news, they retail for $220 a set, and $345 fitted, if we can get 5 or more cars, we can get them @ $200 a set and $325 fitted.
Bad news, they only have the luminous ones, such as this:

Personally, I am only looking for the plain white ones that do not glow at night, but he cannot get them.
I'll still check with UAS and see what they can do (obviously, they can't do the install, but it shouldn't be that hard)
