First, you must Register or Login at Marlboro’s website.
(You will be asked for personal information such as your driver’s license number, etc. This appears to be for age-verification purposes.)
When you login and enter site, click on “Marlboro Country Rewards” when it pops up.
Otherwise, you can click on “Promos & Offers” in upper right hand corner of the site. “Marlboro Country Rewards” is on the pull-down menu under “Promos & Offers.”
I was able to choose from four different free gifts: leather key-chain thing, bottle opener, handkerchief, or coupons.
