I like Aish — as a resource for information on all things Jewish.
And now they’re giving away an IPod monthly.
(I’m not sure if this is a lunar month or a solar month.)
All they require is a name and email address.
Those who register are subscribed to their weekly emails, and must remain subscribed for at least 60 days. But comparing the cost of receiving a weekly email (reading it isn’t required), to the magazine subscriptions or other methods of entering ‘free’ Ipod giveaways I’ve seen on the net — this certainly wins.
