Offer is here

Can't see an obvious catch. At first I assumed these were the first two of the series and you would be sent others for approval - still no risk but you have to go to the trouble of cancelling to stop them sending.
But in this case they claim that nothing further is asked.
My guess is genuine. Of course they aren't really worth £30 - I guess they paid more than the £2.99 but not much more. I assume that this is a slight loss lead to get names and addresses of people interested in this stuff so that they can send out further offers (that are profitable to them) in the future.
Cheers,
Nigel
