And there may be 101 for the checklist! Damn.
There's a checklist in every pack, so you'll get 8 of them in a box - what a waste.
If there are 50 puzzle backs, but only 45 will form five 9-piece puzzles, why not put the checklist on the other 5? You might not get one in a box, but you wouldn't get 8 of the same one. I'm guessing the other 5 are examples of the completed puzzles - again a waste since the sticker itself is an example of the completed puzzle. Personally, I would prefer to have no puzzle backs and just a 50-card coupon back set. The puzzles add no extra enjoyment to the set for me.
I'm thinking that even non-mixed base sets are going to be expensive on the 3rd party market, and the hits are going to be incredibly expensive. I guess we'll just have to wait and see. I'm an old person now who's jealous of Pat's being retired, so I'm saving my money for retirement too.
