How much money is it to buy a minecraft server

Answer 1

That, my friend, you will have to find out specifically for yourself for looking up where to buy Minecraft servers.

 

But, generally, they can be anywhere from free (Bukkit servers - smaller) to $20 (larger servers) monthly or yearly.

 

I'd highly recomend Craft Bukkit Servers if you are looking for up to 20 player slots in a server free.
