Got an email from Marlboro Black saying "Get a $10 Amazon.com Gift Card Offer and Discover Collaboration in Its Rawest Form".
Clicked the link and it says my gift card is on the way. Might be targeted YMMV.
Some slick dealers are saying they needed to click the link multiple times for the offer to show.
It took about an hour to see this in "order status". I received my digital code just a few minutes ago.
