I was able to finally get mine to Submit after I shut off my pop-up blocker but I didn’t get a coupon. Several people are having luck with it. So I hope you are able to get one. Good luck if you try!
UPDATE: I was finally able to get this to work! After you click on Submit, you should get a Bricks pop-up box to fill out your name/address info where they’ll send your coupon. I had to close out of Facebook, sign back in and upload my photo again to get it to work after I shut off the pop-up blocker.
