I wish I had cards to send you. Completing sets is a diabolical sales tactic. It's referred to as the "Coupon Collector's Problem" and it grows logarithmically with the size of the set. The average number of stickers you need to collect to complete a 100 sticker set is over 500, and that assumes that the cards are equally likely. If they make some stickers more rare, that number grows even more.

Getting many duplicates is more common than you expect. If I calculated it correctly, the chance of getting five or more stickers of at least one random player in the first 100 stickers is almost 30%.

[If someone want to check my path for the duplicate problem, you have a 0.34% percent chance of getting five or more of a specific sticker, so the odds of getting at least one player with five or more in the first 100 stickers is 1-(1-0.0034)^100. ]

I love the World Cup, and I am glad you have found your way into it!

For me, the World Cup always comes at the exact right moment to revitalize my love of soccer. Club soccer is played at a higher level and I very much enjoy watching it, but after four years it tends to drag a little bit. And then the World Cup comes with somewhat worse soccer but absolutely spectacular fandom and it just re-energizes me.

Maybe somebody should write a book about the experience of being a fan like that.
