I want to purchase the Polished Aluminum Fender Strakes. The lowest price I found is $195. Does anyone know of a lower price?

Rosenthal Mazda's Finishline Performance has them for $186.
Showed it to my dealer and they matched the price to keep my business.http://www.finishlineperformance.com/cgi-bin/shopper.cgi?key=RX081003&preadd=action

Purchased mine from Rosenthal Mazda for $158 (delivered) off eBay:

You could contact Rosenthal Mazda and ask if they'd meet that price or wait a bit... they'll come down.
