1. Fill a double chest with shulker boxes filled with cobblestone
   
2. Turn the chest into a cobblestone shop
3. My shop now has 93,312 cobblestone available for players to buy
4. (this should also work vice versa, so when you sell cobblestone it goes into the shulkers)

A shop setting could be added to toggle shop interaction with items inside a shulker box to satisfy the 2 players who store items they don't want to be sold in shulker boxes inside their shop container.

SHOPS WOULD NOT BE ABLE TO INTERACT WITH ITEMS INSIDE A SHULKER BOX IF IT IS IN THE PLAYERS INVENTORY

 

Support!!

We can also save our hopper count with this feature.

 

I think it's a good idea, though I'm unsure how well it would work and fit in skyblock.

 

It's effectively the same thing as a normal shop but with a larger container.

 

This is a really cool and good idea
