I have noticed lately people bidding up to £40 for a freesat card for channel 4, 5 and sky 3. These cards are usually ex contract cards which will work...until sky decide to turn them off, and if they are blue...
Sky are currently offering freeview cards for £20. They will also default this card to your local bbc and itv regions. Ex subscription cards do work usually for ch4, 5 and sky 3. Hope this hels someone.
