Regal Entertainment Group, the company behind movie theatre chain Regal Cinemas, is aiming to drive last-minute holiday sales online and on mobile devices by enticing consumers with a free $10 mobile-optimized Regal eGift card for every $50 in eGift cards purchased. The eGift cards may redeemed via Google Wallet at the concession stand, and can be accessed with the tap of a finger on a mobile screen. Regal Entertainment hopes that this incentive, which is available through Dec. 26, will fuel more shoppers to buy movie tickets online during the busy holiday week.
