Great company to do business with!  Ordered a Thule 916XTR bike rack for my car and their prices blew away everyone else on the 'net!  Ordered on Sunday, they shipped on Monday and sent me a tracking number that night.  Super fast shipping and great communication! I'll definitely be coming back to Autoplicity again!
