Before you (Community say this is duplicate i have searched and couldnt find anything like this sorry if it already posted)
I was think how about the giffgaff have 1 goodybag like with BB ads on so the person does have to buy the ads on and plus buy the goodybag afterwords (or the other way around)
and I think new users are going to find it quite dificult buying goodybag and ads on.
when the bb service is commin out you have to buy the goodybag and then plus you have to buy the BB ad on to get BBM and all that
But how about a goodybag thet covers BB ad on.
