You can currently grab the Samsung Galaxy S II from e2save for free on a 24-month contract, at £18PM. My calculator tells me that’s £432 in total. To view the deal, hit the link, click Talkmobile and scroll down to the bottom.
For your monthly £18, you get a Talkmobile (Vodafone) allowance of 300 minutes, 1,000 texts and 1GB of data.
