Shop access commands

On any other raid server I know, it is possible to buy/sell things from the shop and check the goods price with commands. This is very helpfull when you sell large amounts of items or want to check the of an item without having to access the shop interface with the /buy command and then search for the item in its category manually. I think this would be a nice addition to raid as it makes some things a lot easier and comfortable.

The commands would be:
/buy [amount] [item] [maximum price 1 item can cost]
/sell [amount] [item] [price per item]
/price [amount] [item]
/Count (Counts the items you have in your inventory of the item you hold in your hand) This is to complement the /sell command for larger amounts of items.

Of course some items have to be restricted however there are 2 attempts to this:
1) disable those commands within 512 blocks of spawn (just like the other raid servers)
2) disable the command for certain items like soups and of course tools, weapons and armour. (I can´t think of all things right now.
