BT Sport on Sky - deals?

[Speed Badger]

Hi all, just a quick random one for any tips. I get BT Sport HD via Sky and was paying £16.99 a month last year/ 12 month contract on 2 sky boxes. Tried to renegotiate new contract a couple of days ago and the best they could do was £22.99 a month on an 18 month deal on one box only, or £29.49 a month on 2 boxes!

This was the cancellation department I spoke to and I followed through with giving my month's notice to leave and still the best was £22.99. Is anyone paying less than this that is getting the service through Sky? Switching to BT or Virgin is not an option due to location and preferences. Any tips or help appreciated!
