Neither of these deals quite match the 20GB for £20 deal they had. But that seems to have finished now and been replaced with these sims:
12 Month Contracts, 4G included, Clubcard points each month and you could decrease your bill each month by £3 by using their Android Xtras app if you have an Android phone!
Also can cap at a minimum of £2.50 if needed!
£12.50p/m (£9.50 with Xtras)
£17.50 (£14.50 with Xtras)
+ you can use all your data for tethering with no limits on speed!
