I just purchased a few RAM mounting items from GPSCity.com and received a 15% discount using promo code "ADVRIDER15" I found it easier to determine part numbers on the RAM website and then search for them on the GPSCity site. It took about 10 days for the order to be shipped as it appears the complete order must be in stock at the same time before it is pulled and shipped. I believe GPSCity is an offical reseller for RAM.
