Cost of 24 month contract @ online exclusive price of £30 per month = £720
HTC Touch HD = £400 (that's average ebay price!)
8MB Wireless Broadband @ £10 per month worth £240
Quidco = £50
Net price = £30 over 24 months = a little over £1 per month!
Note : I know the broadband is limited to 10gb a month download limit but firstly that is MORE THAN enough for the average UK household who use 4gb per month and its equivalent to downloading say 10-15 films a month, secondly having previously been a capped user with orange broadband they never contacted me regardless of how much I used and I download films and stream football matches online all the time!
Also this deal may be more relevant for you if you're actually looking for a broadband deal as well.
