Beer bottles unlock free online movies with a tap

Combining product purchases with free promotional gifts can sometimes be more hassle than it’s worth — often requiring consumers to collect and send off coupons or enter a code online and hope someone else hasn’t already got there first. Now Dutch beer brand Grolsch wants to make enjoying a lager with a film easier, with it’s Movie Unlocker service that gives customers free access to on-demand video with a clink of their bottle.
