Totally awesome!! thank you

Great buying experience

Billing/shipping db is a little quirky.

very easy to find part

Like other customer reviews, so i hope service is consistent.

Although you don't offer free shipping to Alaska at least you will ship and not charge extortionate rates. I was astonished how quickly it arrived.

Found the part we've been searching for, for two years...

didn't add shipping like other site did after saying free shipping
