This is a really terrific article, thanks for putting it out there. If I can make a comment about the "Everybody Loves Bundles" section: your idea of a discount for past customers is a great intuition. This is called an "upsell" - prove the excellence of your product line with a low-margin easy sell, capture the user data and permission, and use their high satisfaction to sell them on your high-margin, more difficult sell. Your most profitable future customers are the people you've already sold something to. Not all "build a list" advice is for shlocky affiliate marketers!
