Autolite has a spark plug rebate going on until the end of the year.

Rebates are as follows:

$0.30 for each copper core spark plug
$0.60 for each platinum spark plug
$1.00 for each double platinum or platinum pro spark plug

The only catches are that you need to get an Autolite rebate form (I got mine at Trak Auto), and have the UPC symbols from each of the packages.

You can find info on this (and other Autolite specials) at http://www.autolite.com/specials/index.html
