I know I'm a little late since Valentines day was a couple days ago, but here's an m&m's Valentines day ad that I found very clever and interesting. The ad promotes a website that allows customers to have custom printed m&ms shipped to them. The "My m&m's" order is not only limited to Valentines day either; it can be personalized with any message (and be used as a gift.)
I think this is a great idea. The fact that you can now even personalize m&m's is crazy but awesome. Consumers who don't usually buy m&m's may be drawn to this and begin to order the "My m&m's" as gifts. Also, it's something new and creative and will draw the attention of many consumers.
