Website easy to use, shipping rate was very reasonable and shipping was very fast

thumbs up so far

Great prices and selection. Very satisfied with my purchase.

The service is great. Wiper refills ordered for my Nissan Leaf did not fit, even though the website listing said they would. I was provided a refund over the phone without having to return the products. So, product listing--1 star; service--5 star

Website easy to use found what I wanted.
