I have just now negotiated this deal with virgin media with Asian Pack.
Initially they were offering £11.5 + £10 = £21.5/month but after lots of negotiation they offered 6month free Asian pack costing £16.5/month.
Sky charges £19/month for the same.
I am not sure this is available for existing customers & Quidco can't be used for this one either.
FYI: This is my first deal so please be gentle or ignore if Asian pack is not for you.
