I am a stingy cow and though I do have a mobile so DCs school can contact me, I never use and £10 credit lasts me a good year or so. And I don't see the point of Sky when you can pay £20 for a freeview box and an old TV does the job as well as any of the new big ones.
But I do think that what you can save by using the computer more than offsets the costs of broadband.
Money I have saved recently by using the computer:
Got £220 back from Mortgage exit fees that wouldn't have known about if didn't have a computer.
Knocked £10 a month off my gas and electricity bills, got 660 tesco clubcard points at the same time (so £24 worth of deals) and also got £55 cash back by going via Quidco, so £175 plus £24 in clubcard deals. Actually it is more than that as get discount for having no paper bills which couldn't have if no internet.
Saved £9 on a Tesco shop.
Saved £70 on car insurance.
Got a £10 Boots voucher from Pigsback for free.
DH has had several £10 vouchers for completing surveys whilst waiting for his work to update.
Have knocked a good £20 off our weekly shopping bill by reading the Old Style Forum on Moneysavingexpert.com and from recipes on here and other websites, so £80 a month as a conservative estimate.
Have cut our electricity consumption by a third also from tips on Moneysavingexpert.com
Save 90p each time I bank online and don't need to go to the Bank where I would have to pay parking and petrol.
Have saved about £150 a year on our break down insurance.
Have saved money on fruit and veg as have grown our own following tips on forums.
Thanks to the internet I have worked out how much interest on the mortgage we can save by overpaying each month, even if it is only a small amount. If we can do it, this is going to save us a good few thousand.
And many more that I can't think of. We are OK financially and in reality wouldn't be able to get rid of Broadband as both DH & I are reliant on it for work so it wouldn't be an option to get rid. But if we were really skint I'm not sure I would get rid of it as I think it would be a false economy.
Also, don't forget that for some people in a dire financial situation it is information provided by other people on the internet about where you can go for financial help and advice, how to manage your debts etc, are they getting the correct amount of benefit that can help them through. I bet there are a good few MNetters who have got out of a tight financial spot due to advice on here and other places on the net.
