Better price than the currys deal posted earlier and deserves a deal of its own as its £15 less which is quite alot IMO. Good for those who can't get freeview. You can also try 4 mixes for 4 months i think. Use £15 voucher to achieve this price.
"This great pre-pay package not only gives you 200 free digital TV channels thats four times more than Freeview, but also 4 months of the 4 most popular Sky Entertainment Mixes. After this point you will continue to receive the Mixes for £19 a month unless you inform Sky beforehand. Even if you choose to discontinue Sky TV you can still carry on enjoying the free channels."
