Absolutely. That sounds like a numbers boosting trick to me. It sounds like a promo thing because all those current books aren't finished are they? Is it usual for humble bundle to put out incomplete collections?
Thats a bit odd. If I choose to pay over $25 I automatically get the trading cards, I dont care about the cards. But it says $13.80 of my payment will be deducted for the cards and only the remaining $11 will be split between Humble IDW and charity.
I'm only paying $25 because I want the majority to go to charity
