Migsec hes using buycraft to make money off the kits. and Rycci you said it wrong its not playername its (name) . btw

If you're using Essentials, you can make kits in the config file. To get that specific kit, just use the command "/kit KITNAMEHERE"

You can find more information on the Essentials config here.
You can get essentials for 1.3.1 here.

(Also I don't agree with Pay to Win packages, but that's just me and my values.)

and can you make me op kit with:

diamond:
hat
top
bottom
shoes
and
weapon

thanks

Very simple, just go to Buycraft website, then Add Package.
Lets say you want to give the customer 1 Iron Chestplate with Protection 4 (IV)
Go to the commands section and put this command: /give playername 307 1 protection
That gives the player ''playername'' 1 iron chestplate (307 item id) with Protection 4
