Monroe is offering a $30 rebate with the purchase of front and rear brake pads from April 1 through May 31.

There's also a $15 rebate for the purchase of just one set of pads.

Just make a purchase like normal from BrakePadWarehouse (http://www.brakepadwarehouse.com)

Then just fill out the Monroe rebate form:

And Monroe will send you a check in the mail.

This is a great deal considering most brake pads are about $35, so you're basically getting one set free when you buy two.
