I did the same about a year ago, good deal. I buy all my Mobil 1 oil from Costco as well, an even better deal.

How It Works
When you enroll in the Mobil 1 Rewards program, every time you purchase a Mobil 1 with SuperSyn oil change or a total of six quarts (a case) of Mobil 1 with SuperSyn, you'll be earning rewards that can be redeemed for Mobil 1 merchandise or a GiftCertificates.com SuperCertificate.
