Create a custom shop via table.
Use that table to open a trade window.
In the example below I used simple keywords to show each different shop.. (Shop A, Shop B, Shop C (A & B merged))
But the uses of this is only limited by your imagination.
Few quick examples of things you could do
-> Different / merged shop based on input from player. (Think of the player saying potions / armor / runes, and then you filter the shop into those categories)
-> Gender based shop
-> Quest Status Shop (If quest requirements met, merge the shops / show different shop)
The onBuy and onSell functions are really simple and can be expanded upon, but that's not what I was worried about showcasing here.
