The link that @FranzF provided is purely for customer by customer basis. So each customers offers will be different.
Best to keep checking the link out to see the best offer for you.
@K10 if you haven't received an offer or you don't get a retention offer, jump on to live chat and ask if they can do anything. In recent weeks I've been given heavy discounts on entertainment and sport by doing just that. The flip side is they wouldn't offer me anything for movies.
Thanks Saint. The other half has tried as have a few friends, they’ve not had much joy. I think for me it’s got to the point where if they want my custom, they’ve got to have a good deal, otherwise it’s sensible to walk away and consider other streaming services.
