Hm, this does make sense, yeah.
So basically for the add-on packs, once we reach 100 orders, everyone gets 3 sets (ergo if we had 108 orders, then it would be 3x108 = 324 actual sets produced)
Then once we get to 150 orders, everyone gets 2 sets (ergo, at 220 orders, it would be 2x220 = 440 actual sets produced)
And so on. This way, we get to reach the MOQ regardless of actual orders, and people just end up getting more keys anyway.
But do we apply this to the base sets as well? Seeing as only the Dolch base set seems to be anywhere near the 300 mark.
As earlier mentioned, if I knew that I was getting multiple add-on packs, I'd probably just get as many base sets to match. Having spares is nice, or I could sell them to my friends instead.
