There's still a bug ingame that is still being fixed. Luckily for you, the Market is open and they charge either half, or free ^ But still, the ingame shop is still being fixed....
It is still ingame, it's just glitched.
They'll fix it eventually, but for now download torishop2.lua and put it in the "toribash/data/script/torishop" directory to fix it.
