Mabye now there should be emeralds in the /shop

/Shop should be left in place to keep a level on the economy.  Without some form of solid base, the server's economy could collapse if a large enough group of players got together to inflate or bottom out something.  (granted, I'm sure an admin or Mod would take steps to prevent that from happening)
I think the buy prices on the /shop are good.  a hefty margin above what an item is really worth.  Some of the /sell options could be modified a bit.  Adding redstone as a cash commodity would be wonderful for inventory space, but the price of selling it would have to be ridiculously low.  Perhaps 2nbz/5redstone  or something of that nature.  I agree that not all things should be added to the /shop buy or sell though, as it will keep that incentive for players to frequent market district more.   So my vote on the poll should be split 50/50

Seastore gets runned by the mayor and TAs of the town of Seaside. It is not an admin shop. As people buy things in Seastore the chests will get space in them and you'll be able to sell your stuff to Seastore. An admin shop selling everything what Seastore sells at the same prices would be unfair competition, wouldn't it?

The price of bread should go back up to 3 because I don't understand why it has been changed to 2 when I put in 3 wheat, sometimes I like to feel a double chest before I sell produce and turning wheat into bread is more compact.

you should and more items to the list

You should add redstone and glowstone dust
