I too signed up for the trial, didn't find anything useful and tried to cancel exactly 14 days or whatever the trial period was. Unfortunately I had signed up on the weekend and they didn't answer on the weekend and my credit card was charged. The good news is they did refund me when I explained this, so they do get kudos for that.
I do have their app on my iPad, which delivers a tip and or recipe every day and I still get the daily emails which are nice to read over occasionally. They usually have a recipe or food advice. The app apparently costs 2.99 or so, which isn't bad.
