Order through Amazon took long time to process.

make sure these cartridge assemblies work on my 2003 Pontiac Bonneville se for the front

For some reason, it originally said I wanted two items. I'm sure it was my fault.

With me. As long as it gets here on time and in good condition. I'm good

went smooth

products looked great, but the descriptions and pictures made it extremely difficult to tell what we are purchasing. Hope we don't have to send it back!

This site was just like shopping at a real store. It was easy to make my order and I was able to do it on the go on my smartphone which is important to me that a site is compatible with handheld. Bravo

Your site said if I signed up I could get a discount of some sort. Did not specify the amount. Would like to have that applied.
