Autoplicity was great, I ordered my springs late Monday night and I received a shipment order confirmation number early Wednesday. So basically 1 business day and my order was out the door, pretty impressive. Can't wait 'till it gets here! Thanks Autoplicity!

easy to buy if it fits

Great prices on a lot of good stuff, shipping isn't what's listed in price comparison, but competitive.

The shipping was fast, although I couldn't get it the first day because they require signature for delivery. I guess it's an added safety measure. Thank you! Will shop buy from again!
