Cheapest

Autoplicity had the lowest price(s) I could find on the individual item(s), and, even after shipping was added, my order still cost less than it would have at other places with "free shipping." It's also nice that you can use something like Google Checkout instead of having to create an account at Autoplicity to checkout...one less account/password to worry about keeping track of. My order was packed well, arrived safe and sound, and arrived well within the expected time frame.<br><br>Great prices, proper packing, and good turnaround...what more can you ask for?
