Just a quick note to RTFR (Read The Freakin' Rules!) and details and checkboxes on ALL sweeps you enter, even if they are ones auto-added or included in the sweepstakesninja program. Hearst magazines (Town & Country, Redbook, etc) sweeps pages contain a feature that auto-subscribes you to the physical publication for that particular sweeps and will attempt to bill you for it. Canceling the subscription via the customer service link at the bottom of the Order Confirmation email you receive is fairly easy... but I've found that several subscriptions cancellation pages generate errors and require a manual email to the fulfillment company to request a cancellation. So save yourselves the hassle and view the entry page carefully before entering!
Just a heads-up to read all your sweeps info carefully - Good Luck!
