Yes we've tested it with digital products and found:
1. With the right product it can increase response by 200% or more.
2. It can also increase the price you charge if you make the first payment after 30 days an installment.
3. You will get killed with refunds delivering digital products this way unless you follow a few very simple tweaks that almost no one is using online or offline.
I talk about the how to make a 30 day trial offer work with digital product delivery in the
Offers Unleashed product.
