Claim is in all three, on the button. It's the accurate verb for what the card already describes: the slots exist, somebody is holding them, and the ask is to take one.
The scarcity itself is the real decision, and it isn't a design question. It's which of these is true. All three are built on The Brief so the only thing changing is where the pressure comes from.
These aren't exclusive. S1 plus S2 is the strongest combination: the market scarcity makes the case that the money is real and already being taken, and the exclusivity makes the case for acting now rather than in the spring. S3 can sit on top of either, but three scarcity claims in one short card is the point where a reader starts counting them instead of reading them.
Is the one-territory-per-market rule actually BMG policy? S2 is the best line on this page and the only one I can't verify. If we do serve neighbouring territories, it has to come off the card, because the prospect it's aimed at is exactly the person who'd know. Same for S3: give me the real monthly cap and I'll set it, or we drop that variant.
