Seems like a brilliant deal to me.
Subscribe to three issues for £1 and get a fiver cash back. The retail price is £4.20 per issue.
If you subscribe to both make sure you make two separate transactions through Quidco.
They do have other magazines for a quid, but these have to be ordered by phone and you won't get the cash back. Also have three issues for £3 of other mags, and although a good deal still, there is less profit in it.
Here is the blurb:
Try evo today with 3 issues for £1 with no obligations. If you're not 100% satisfied, simply cancel during your introductory period. If you like what you see, your subscription will automatically continue at the LOW RATE of just £21.30 every 6 issues, saving you 15% on the cover price
