All you have to do is post a contest that looks like the example below and mention it a few times before the deadline.
We'd even mail the gift card for you so it's virtually no work for you to participate in this promotion.
You may even want to add your own gift certificate to the package to increase the engagement of your fans.
We recommend starting the promotion on Friday, April 29th and picking the winner on Wednesday, May 4th which is a great day for Star Wars related puns... "May The 4th Be With You as we pick a winner in our contest"
To participate in this promotion, please respond to the message that got you to this page or contact Rafi at firstname.lastname@example.org or at the store 518-272-2000
