I wasn't about to spend $40 for a subscription, but found it for $19.97 at http://shoppervalues.com/detail.cfm?id=42279
What you have to do is give them an email address; in exchange for the cheaper rate they promise to send you occasional (no more than once per week) email advertisements. I've only received 2 or 3 of them over 6 months.
The downside is that they take a while to start the subscription: I waited 8 weeks for mine to start. To me, the saving was worthwhile.
