Al's has the Kuat NV 2.0 hitch rack on sale for $471.75. A 10% off code "ALS10" brings the price to $424.57. Original MSRP for this is $629. Pretty sure this is NOT the original NV and is the newer 2.0, or at least I damn well hope it is.
Looks like they have stores in a couple states, so some people may get taxed. Shipping is free.
Note: Best price I've seen on this previously is $503 (20% off MSRP)
They also have the NV 2.0 2-bike add on down from $429 to $321.75 before the 10% off code.
