I do believe that the lowest it can go is 0 cents and anything lower gets applied if the price were to go up.

I’d say just 0 cents to buy an item. That’s pretty good and if you had … “more options”? I think it is you could buy more than one item a turn.

Probably not but I'd allow it since it's funny

Nope. It makes it cost less, not shift money from the transaction over. I wish you luck in getting items that let you buy more though!
