BT's big Black Friday game was to give you big bucks if you sign up for one of their broadband deals. Regarding promotions, she certainly can't dispute this kind of widespread call. And it wasn't an average sum either. Sign up for the cheapest BT broadband offer (in our opinion, at least) and the ISP promises to send you a €120 worth of prepaid MasterCard to spend on anything you want, whenever you want. The home internet plan in question is the BT Superfast Fiber Plan, which offers fast average fiber speeds of 50MB, unlimited landline calls on weekends, and free activation. And all for just €28.99 a month. And another thing we love about this promotion is its sustainability: almost every other provider has expired their Black Friday broadband deals. This leaves BT mostly until its own offer ends on Saturday night.
