Perfect so far!

Had to update cart cause it showed the wrong amount then kept adding instead of deleting amount so had to start from scratch.

I found what I wanted.

Shipping was 5.00 on a 1.99 part but considering ebay was asking 18.00 for it I'm very happy

So far, they did good getting my package to me...downfall it was opened from whoever was subcontracted to send it to me. however they promptly have provided me with a return slip and we will see where it goes from there. they were quick to help fix their problem as long as i had pictures of what was wrong. still cheaper than anywhere else.

Great product and was the cheapest I could find. Easy to order and shipping information e-mailed to me the next day.
