Voucher or licence.

U should know how licence is applyed to the account. Its simple, make the payment and wait until the further "process" is done (by lfs devs i assume).

The voucher, u can buy it and then give it to your friend for example. He types in the code and unlocks S1/S2.

Edit: I think i misunderstood this a bit. NotAnIllusion answered the question. :P
