Ordered a sling to store my roof rack. There was an issue with the supplier which was quickly resolved by the Autoplicity staff. Great customer service -- most responsive I've ever seen.

Best prices around.

Rather amazing and uneventful service in this day and age.  Ordered a Thule bike rack for my Nissan Murano.  It was in stock (unusual for high-end specialty products), shipped the next day, and was on my doorstep in a few days (excellent for a 60 lb. large box).  I'd buy anything from these people without any reservation.  AND, your order is insured - completely superfluous.  Oh, and did I mention, the lowest price I could find ANYWHERE, and not by a few dollars - a lot.
