I suspect in your areas they are doing a special deal so not their regular pricing as 500Mbps is never normally £32.99
Altnets can do 500 for lower... where available.
£24.99 here at the moment for a 12 month contract. I thought it was a special offer for me only

. It did not say it was, but I just thought it was.
150Mb/s is £20, if I had known that when I went for mine I would have gone for that instead of the 500Mb/s. Still never mind.
12 months contract, so that is good.
