Product reorder subscription plugin allows you to make a set of products that have a lifecycle (defines how many days customer will use the product) and give an ability for customers to subscribe on it. In other words, it is a modified promotional notification system replacement for nop recurring products.
If you sell services/products that need repeating at regular intervals (for ex. cosmetics, sports nutrition, licensed software, insurance services etc), then this plugin is definitely for you. Customer will always stay notified when it's time to make a reorder. Customer will also have an option to subscribe/unsubscribe from a product manually.
There is a free demo version available with only one restriction - up to 3 products can be added for subscription
