I have made a shop at the Grinder Warp. It is large enough to have a few more shops, and if it becomes popular, I can always add more floors. If you plan on building there, please make sure you keep everything at a half level or on non mob spawning blocks. Otherwise, there is a cake vendor and an Iron block vendor for emeralds. More to come.
I will eventually roof it off once I see how many people want to build shops there.
