ipod mail in rabate?

hi.
i just got my mbp and ipod from the apple uk store.i received it by courier.

i have question about the labels i have to cut for sending for mail in rebate.

with the notebook there is one box of the computer and anther that is the whole package.on both boxes there are the part numbers and serial numbers
so which i have to cut or both ?

for the ipod there is only one sticker so its easier u don't have to cut anything.but do I have to cut from the outside box?

thanks
