I think Virgin have changed the extra offer for VM home customers at least twice in recent times (within the last year perhaps).
They used to offer £5 off SIM-only tariffs for VM home customers. Then that stopped and they offered the £5 SIM-only tariff exclusively for VM home customers. Then that stopped, and now the benefit for VM home customers is "Unlimited calls to other Virgin Mobile phones" (which you possibly used to get with the previous offers as well, not totally sure of that though).
And they used to have some 12 month SIM-only tariffs for a while I'm sure. They seem to have been tinkering with what they offer with some regularity of late.
