I waited till this got cleared to make sure it worked, and it has so i wanted everyone else to know.
This will only work if you have quidco as this is were you are making the money.
If you go onto quidco and search for O2, third option down, and click into it they are offering.
£23.33 for SIM only products
£35 for Pay Monthly (Contract) (single commission per order basis)
£3.50 FOR PAY-AS-YOU-GO (SINGLE COMMISSION PER ORDER BASIS)
£40 FOR MOBILE BROADBAND
110 for Samsung Pay Monthly Contract Sales (G600 Mighty, U900 Soul, U800 Sleek handsets only)
I highlighted the important 2 in Bold.
So by going through quidco, to O2, and getting the pay as you go dongle you are straight away making a profit of 14.60 pounds for nothing.
I have checked my quidco account, the order has been tracked, verified and in my bank account.
Hope this helps people out there.
