Came accross this coupon on the internet and it saved me 10% off of the Escort 9500ix. I am assuming this code will work for most items on the website but I can only confirm that it just worked while I ordered the 9500ix.
Code is radarroy
$450 (sale price) - 10% discount code = $405 + free FedEx 1-Day Shipping
(Tax only in CA, NE, and OH)
Hope this helps!
