Warning: the biggest deal pays here.

Deal. One deal per wallet per box, 0.001 to 0.1 ETH. You need 2,000 $DEALBOX in the wallet.
Close. The box closes 20 minutes after its first deal. Deals after that go to the next box.
Pay down. The biggest deal keeps 60%. The other 40% of it goes to every smaller deal, split by size, on top of each one's own deal back.
Ties. The deal made first stays biggest. A lone deal is refunded in full. No cut, ever.
