Not strictly YNAB related, but if anyone has their Broadband contract coming for renewal, I got a stonking deal with NOWTV (Sky).
I was paying them £43 per month for 64mbps broadband and anytime calls. They sent an offer for the same package for £30. I phoned up and the man said 'I can go better than that...£22 per month.' I said 'Oh that's great - it's a pity I've just paid this months bill!' Then he said 'Oh, don't worry, I'll credit your account by the difference, and by the way, you won't have a bill at all in November.' So I've gone from paying £43 per month to paying £22 for October, £0 for November, £2.14 for December, then £22 from then on!
Back to YNAB, I do think it helps to see it all written down and then it makes you try to cut things! I'm going to try to menu plan, I think, to bring grocery costs down. There's no point in trying to save money on Gas/Electric, but if I can cut other stuff, it might take a bit of the sting out of the bill jumping from £106 to £233 over the last few months!
