The Complimentary plugin allows you to automatically give a subscription to a second product when a user signs up for another product. You have the option of making one of your paid products give a free value add to your customer. Think of the marketing potential! "Buy our premium information product and receive totally free access to our customer leads area" obviously you will need to make your own sales copy. You are able to add a free trial style complimentary or give your paying subscribers access to a permanent 'lifetime' reward for joining as a paying customer. The Basic version is available to subscribers to the Membership Academy. The Advanced version is available at JLogica for US$37.50 (Advanced adds the ability for a time limited complimentary as opposed to lifetime only in the Basic version).
