This promotion isn’t limited to Dollarama, but the best deal for the promotion is when you buy the qualifying products there. Every year for some time, Cineplex has had the promotion where you get a free movie ticket for purchasing a certain number of specially marked candy products. The cheapest price you will find for the bags of M&M and Skittles products that are specially marked, is $2 at Dollarama. They do not always have the specially marked bags when the promo begins, but if you have a look now you should be able to find them.
You will have to purchase 5 bags for $2 each and hang on to your receipt to upload through the link below. Most stores seem to have Caramel M&Ms, Peanut M&Ms, possibly Starburst, and an assortment of Skittles varieties. Just a reminder as well, that unlike previous years, you do not have to open the product to get a PIN code for your free movie ticket. This means you can buy the candy now and save it for stocking stuffers, etc.
