So, I was checking this deal out for my sister and her fiancee and it looks like o2 is giving away 2 months free on ANY broadband package.
Quidco is currently tracking at £50 per month. (NOW TRACKING AT £60)
If you take the Standard Package, this is how the maths can work out for you (based on first 12 months)
At £7.34 per month, 2 months free, so only 10 months are payable. thats £73.40 for the year, then deduct £50 quidco from that = £23.40. Divide that over 12 months, and monthly cost essentially works out to be £1.95 a month. (IF QUIDCO DOES INDEED TRACK AT £60, THEN COST IS ONLY £1.12 PER MONTH)
For the other packages,. Premium would be £3.68 per month, and Pro would equal £8.66 per month.
