This is a device I made that helps trade with and store Villagers. It is infinitely expandable if Your good with Redstone/get the pattern. so anyway there's not much to describe, just download it and try it for Yourself.

Note: When the Minecart dispenser is empty use /give (Your MC Name) 328 64 nine times and use those.

Note: Since cheats are on you can gamemode yourself to use it on survival

Note: There are signs to tell You what to do.

Thanks for looking! leave a diamond if you think its cool!
