I was stoked that after reading other reviews that there was no shipping charges for my purchase. Thank you!

love it cheep prices on parts

Couldn't call to check predicted shipping arrival date.

Arrived qickly and looks great haven't jnstalled yet but looks pretty straight forward

Lowest price and free shipping life is good

I may need to return the unopened part and i don't see the policy and procedure. Ill have to search on the site page. All legit solid businesses I've worked with in the past made this very clear and up front. Not to say you didn't I just haven't looked yet and its not in your face obvious.

Great price, would purchase from Autoplicity again.

All Good

No fault of Autoplicity, or mine, but i needed to return the items. A 15% restock fee would be applied, way to much!

Love the amazon checkout
