I consider myself a very good online shopper. Especially for auto parts. When I ordered a set of Eibach Prokit Sport Springs, I thought I would give Autoplicity a try. Online reviews were very good for this retailer and I am very happy to report that my springs were delivered via FedEx within 5 days of ordering! I asked for an update via email after 2 days and received an immediate response. Happy as can be, and I'll be back.
