Shops
From Big Sister Minecraft Server
Shops are a very useful places to go to on the Big Sister server, especially if you're planning on doing a large build or pixel art. At shops, you can exchange Cheese, primarily Green Cheese for different blocks and items. Before the July 3, 2017 Update, shops were created by using command blocks that would exchange cheese for items. Now, however, shops are populated by villager merchants who will happily take those emeralds off of you.
This page will also contain a semi-up to date list of shops, where they are, and what items they sell.
