Piglin does not have a server shop. All shops are made by players, and you can create one too. If you are looking for a shop, use /warps to look through the warps. If you are interested in creating your own shop, this tutorial will explain it to you!
How To Create a Chestshop
Step 1: Go to the location you would like to build the chestshop. This can be in any survival world.
Step 2: Fill an empty chest with the item you want to sell.
Step 3: Shift right click to place a sign on the chest, or place the sign above the chest.
Step 4: Write the quantity on the second line.
Step 5: Write ? on the fourth line, it will automatically be updated with the name of the item when you’re done.
Step 6: On the third line, type a B if you’d like people to buy items from you or an S if you want people to sell items to you. Also on the third line, include the price without a currency sign.
Step 7: Close the sign gui and you are done! The first line will autofill with your name if you did it correctly.
Step 8: (Optional) Setting a warp to your shop will help players find your shop and buy from it. For help on setting up warps, click here.
Once you have the basics down, you can try to create more complicated shops. See below for more examples
You can place shop signs anywhere around the sign. The above example shows just one of the many locations you can place them.
You can make a shop that gives away stuff for free by putting B FREE on the third line. You can also make a donation shop where players can donate you items by putting S FREE on the third line.
You can put any integer number on the quantity line. You can use this to sell multiple stacks at a time.
You can make a buy and sell shop using one just 1 sign. On the third line write B and then how much you want people to buy for and then write S and then how much you want to sell for.
