It was a easy transaction and shipping was pretty fast. Very happy with this company, and will order again!!! ( actually already have)

Received ordered trailer hitch same week. Fitted perfectly. Like the product. Price was the cheapest, but quality is good. <br>Thanks Autoplicity

reasonable prices and free ship

Shipping took a little longer than quoted

so far...quick/easy and very nice. lets see about shipping time and returns (if necessary)....???

Best price for the particular part I was ordering. Their staff/customer service is very helpful and polite, but unfortunately their shipping times are lacking. Before ordering on Monday, I called to verify the item was in stock, and asked what shipping method I would need to ensure it would arrive before Saturday. I was told 2nd Day Air. I ordered that same day (around 1pm). The package wasn't shipped until Wednesday evening, AFTER I called and inquired a to why it hasn't moved. What really upset me though was that the package ended up being shipped UPS Ground anyways, to arrive here the very next day. Long story short, I shouldn't have had to pay the extra $20+.

Great checkout process!

Filter was as described, quick ship, great price, thanks!

Very pleased with Autoplicity's fast and efficient service. The part I ordered fit and looked great. Will definitely consider Autoplicity for future orders. Thanks.
