What the Money Shop sells, what it costs, and which upgrade to buy first.
Updated

Cash has three jobs in this game: buying gym capacity, signing fighters, and backing bets. The Money Shop is where the first two happen, and until now no site had published a single price from it.
| Item | Price | What it does |
|---|---|---|
| Gym Expansion | $100,000 | Expands the gym |
| Training Cap: 0 > 1 | $200,000 | Raises the 10-training ceiling by one tier |
| Punching Bag upgrade | $64,300 at time of capture | Station upgrade; the bag is labelled +1 PWR, +2 DEX |
| Rotating Legend slot | $2,000,000 – $5,000,000 | Buys a Legend outright, on a refresh timer |
The shop carries a limited-time fighter offer on a countdown — we caught it with 1 hour 36 minutes remaining. During that window two Legends were on sale on red cards: Larry Holmes at $2,000,000 and Sugar Ray Robinson at $5,000,000.
That price spread is informative. Legends are not interchangeable — the game itself values one at more than twice the other, which is the first hard evidence that a real power ranking exists inside the Legend tier.

Gym Expansion at $100,000 comes before the Training Cap at $200,000, for a simple reason: the cap only helps a fighter you are already training, while extra capacity lets you run a second fighter through training blocks in parallel — and leagues gate on roster averages, not on one card.
There is also a free tutorial slot: a popup states "You can now have multiple fighters. Open the shop to buy a 3rd slot," so the second slot arrives without spending.
