So you want a new driver, but money is tight. Callaway and American Express are teaming up to help you justify shelling out your hard-earned money on a new club: Buy a driver, get free gas.

Here are the basics:

1. Buy a Callaway FT-i, FT-5 or Hyper X driver before July 15 from an authorized dealer.

2. Complete a claim form by registering at callwaygolf.com/gascard

3. Send Callaway your original receipt, UPC bar code, the claim form you received after registering and the serial number of your new driver by July 31, 2008.

4. Await your gas card, which according to Callaway is usable almost everywhere you can buy gas with an American Express card.

The value of the gas card is based on the driver you buy:

Callaway FT-i = $100
Callaway FT-5 = $75
Callaway Hyper X = $50
