Shop/Gallery Size Calculator

After you initially pay 150 NP to create your (size 1) shop or gallery, you can only fit a total of five items into it. Fortunately, you can upgrade your shop or gallery so it can fit more items. Upgrading to size 2 will cost you 200 NP and give you space for a total of ten items, and from there upgrading to size 3 will cost 400 NP and raise your capacity to fifteen items. Each upgrade costs 200 NP more than the last, and gives you room for an additional five items.

Juggling all these calculations in your head can get a bit tedious, so this calculator has bravely volunteered to do the job for you. Happy number crunching!
