12 month contract sim only deal
for £10.50 a month:
300 minutes
500MB internet
Unlimited texts
750MB BT Openzone Wi-Fi access

now you can get this deal on Vodafone, but if you use Vodafone Business instead you can get £100 cash back for a sim only deal, which makes it £2.17 a month!

however if you use quidco through personal Vodafone (i.e. not business) then its only £30 cash back which is £8 a month, and still not bad.

Vodafone Business 300mins unlim texts 500mb Internet, £10.50 /month, or £2.17 after quidco
