Advanced Economy Shop Add-on 1.21+

There’s not much of an economy in Minecraft—Villagers set whatever prices they want for any goods. We believe it shouldn’t be like that, and prices should change depending on supply and demand, just like in a real market. The mod Advanced Economy Shop brings a realistic trading system with dynamic prices. Players can watch price fluctuations and use this to make profitable deals.

Once you enter the world, you can use the command !shop to open the shop menu. You’ll be able to buy various items in available amounts at fair prices. There’s also a purchase history available.
