All is good. We shall see how the shipping process goes.

best price , easy transaction

Straight forward so far so good. Update: Upon receipt of shipping confirmation email I received a tracking number but no ETA date or time and no apparent way to find this information so I could arrange for somebody to be present to receive item. I reached out to customer service through email and never received any form of response beyond auto reply that my inquiry was received and a ticket number was assigned. Fortunately delivery did work out with my schedule and driver was very professional and helpful. I would order from autoplicity again in the hopes my inquiry had just slipped through the cracks and future orders would have some form of ETA when and if a person is required to be present for delivery. Time of order, to shipping, to receipt of product was very quick (within a week).

would like to see more info/ details in the description

First off, I LOVE my new shipments! These guys had everything at super low prices, and the shipping was phenomenally fast. It's all working great, and imm definitely buying from these guys again.

Great prices and fast shipping.
