Hi sorry but I have just bought a zgemma 2star satellite box with gift it was a case of plug and play works great no problems at all but the gift is only for 3 months and its £30 I have been told that you can buy them for 12 month for the same price but don't know where or how to purchase these and don't know the difference between n-line or c-line the person I bought the box off said that my gift is an a-line can someone please explain in more detail or is it a case of ebay.
