Got one of those for wine yesterday - get the initial cheap (but not free offer) purchase, and then only through well-learned suspicion do I check through enough to realise they've auto-enrolled me on a £25/month subscription.

On the upside they answered the phone immediately outside office hours and it was all cancelled in less than 30 seconds, so it's not always a hard sell on the phone

LinkedIn's "free trial" does this too (although they are /somewhat/ transparent with it). They send invites to trial their premium product pretty regularly, but in order to activate the trial you have to essentially sign up for the service, and then remember to cancel again before the trial runs out and you start getting billed.
