Regular moviegoers will notice that Regal Cinemas stopped its weekly mobile coupon at the end of 2013. Luckily, for cheapskates, it’s back. However, it’s now a monthly mobile coupon. We love any chance to save money at the movie concession stand, given the expense of tickets. This month, you can get $3 off any popcorn at Regal Cinemas — access the mobile coupon here. You can use the coupon once per day through February 28. No printed coupons will be accepted. You must show the coupon on your mobile device to get the discount. With the coupon, at most locations, a small popcorn is $3.25, a medium is $4.25 and a large is $5.25. For groups or popcorn lovers, the best value is the large because it comes with one FREE refill.
