I"m glad you picked the right solution.
Okay - in Holland just a few weeks ago - Albert Heijn (the biggest supermarket in Holland) had a special marketing stunt; whenever you spend more then €10 on groceries you get a pack with 5 football stickers. Yes. It's very stupid, but you wouldn't believe how crazy that got! After one week of the stunt there was already a kid beaten up for his stickers etc. , and 50 kids were standing in front of each supermarket in order to get the stickers of older people who didn't want them. But, they did want them. Everybody wanted the stickers.... how Dutch. It's free, so everybody want's it.
I have them too though
