If, like me, you’re a BT broadband customer, you may be slightly puzzled by what turned up in the post this morning.

The letter I received actually appears to be offering something for nothing – in fact, less than nothing.

It says I can pay £2 less a month and make internet and phone call savings plus have a free “hub phone” and “home hub”, whatever they are. (Yes, I know I should have been paying attention to the adverts with that nice bloke from Love Actually).

I’ve read the letter twice and still haven’t spotted the catch.

Can it be that BT is cutting prices in a bid to retain customers? Or is something more sinister going on?

If anyone has any thoughts, please let me know.
