coin tosses can be combined to generate a larger number.

Hey, guess what! When I was playing cp today, the purple dragon costume came out for like 500 coins. I had like 200. I clicked buy and it said: Would you like to buy undefined for 500 coins? I clicked yes but I don't think I got it. Weird, right?
