cannon ammo, where do you buy it?

[ASuperStitch]

What is the type of shop that you find cannon ammo in? I have tried the shops with the crossed swords and the shops with the gun and the boat repair shops and can not find this ammo. I have bought it once but can't remember where, good grief it is heck to get old!!!!!!!

Thanks in advance.

It's in the gun shop, maybe the second or third tab.

It: it's the thir tab, it doens't show anything but it's there.

thanks, I did not look there because the tab was blank but you are absolutely right.

thanks again
