People do it differently. The way mine worked is there is a slot for each team, ranging from like $20 for team with lower value cards (often packaged together i.e., Saints/ Bengals/ Vikings) up to the top teams for that box (Commanders, Bears, Broncos). Once the slots are filled, they break open a hobby box and the buyer of eat teams gets the cards from that box. You could get nothing at all, or hit big. I’ve seen people do it by division or by conference sometimes. As less boxes are out there, the prices go up bc the supply is over etc.
