Autoplicity had the part I needed at a price half of the local autoparts store. Shipping is reasonable when multiple items are purchased, for one item the shipping charge seems high. Took them awhile to ship the order(3 full business days) which I think is too long, but they are the cheapest. Only other comment was I usedAmazon payments to pay and then got a coupl of emails from autoplicity asking me to complete my order, which I had already done.<br>Overall a pretty good experience and an excellent price.

Very easy and simple check out

so far so good

Very happy with my order with Autoplicity. Hands down the best price on brake pads that I could find. One set took a little longer to arrive since the manufacturer was to send them out, but a call to customer service yielded an explanation and a few days later they were on my door step.

Fast Shipping, Great price, Parts were well packed

Very easy order process. Thanks

Thanks.

Good

Great!
