It actually does mention the price of the cartridges, in the store. $50 each, with discounts if you buy more than one.

Ah, so it does. Still doesn't say how big they are. ("1 Cartridge prints 13 to 14 mid-sized creations" is a magnificently useless piece of information. The only number that matters here is kilograms. How many kilograms does it mass? Why doesn't it say?)
