This is my full tutorial on How To Build An Automatic Store or Shop in your Minecraft Bedrock Edition or MCPE vanilla survival world. This is a 1.16 & 1.17 build.

After building this you will be able to sell your items to friends and anybody in your server. It gives trades at a 1:1 ratio, meaning for every item the buyer places into the hopper, they will get 1 item of their choice in return.

The redstone is very easy to set up and it is infinitely tileable to fit whatever space requirements you have.
