just discovered that i could buy pre-paid amounts of premium subscription via an VPN through india (using Hola) to get cheap pre-paid youtube subscription... this subscription can stack so i have bought over 7 months worth...
just enter any fake india address on card payment it still works (some random hotel address is a good one to use)
139 rupees for 1 month = ~£1.34
399 rupees for 3 months = ~£3.84(check that your bank has reasonable currency exchange rates, some extra bank fees may apply)no more adverts for me! happy days.
