I'm not 'devastated' about this particular product, but I know the feeling. I can think of half a dozen products I'd have bought had I known they were going to be discontinued.
There was a thread from a couple of years back suggesting that Eden add some kind of warning before a product is discontinued, perhaps as an alert users could sign up for. I'd be very much in favor of that, but I don't know what kind of a technical challenge that would pose, or whether Eden even knows whether they're going to discontinue products before they go out of stock.
But if it's possible, I think it would be greatly appreciated.
