Prior customer of EB, receive mailing list emails.
Got another $10 certificate email this morning, email titled "We Got You A Surprise Gift".
Slickdeal part is that by scrolling down, limited time offer through 5/23, sign up for Adventure Rewards, automatically upgraded to Bronze level, which means free shipping.
Looks like you have to follow the link through the email, trying to go through their site didn’t activate the upgrade.
So, ymmv based on whether you got the email or not.
Was able to use the $10 cert and buy a bag for free, no shipping costs.
