As I use David Frey's "12 Step Formula" so much when writing sales letters - I ended up throwing a little software app together so I don't have to keep referring to the document. This way I can fill out each step, then have the software spit out a final draft, ready to edit.
Download it for free below, and let me know what you think! :)
Oh, and be sure to read through the 12 step formula at the copywriting page of David's website (as I only left basic "prompts" for each step in the software).
