Pretty easy to use, however it created an unlimited supply of my free product (which I did not have), and I only discovered this when a customer selected it and i no longer had stock. Also, the app doesn't work on Mac/Safari. Which is really annoying as I run my whole business and shopify on my mac. Told I need to get another browser. For that reason, am deleting the app.
you can edit stock of your free products (gifts) in products administration.
I am so sorry about Mac/Safari, but shopify do not allow to open app inside their frame in this browser - developers can do nothing about it :/
I saw you installed app again.
Can i help you with something? Write me back if you will need help :)
