Are You Using “One Time Offers”?
If you’re not, you should be. “One Time Offers” are basically upsells… you get someone to do something… opt in to your list or agree to buy a product. Once they’ve done that you show them an offer page and try to “upsell” them from the basic action they just took to a “better” offer (usually more profitable for you!)
The only difference between an upsell and a OTO is that the OTO is supposed to be a “once-only” offer. As with any marketing tactic, OTO’s can be overdone… especially when it’s a freebie being offered and you have to go through multiple “no, I don’t want the glorious offer” clicks to get to the freebie.
However, when they’re done right (offering something closely related to the original action and at great value) they can be a very useful mechanism for making extra profits. After all, how many times are you sold the “super size” version of something when you’re making a purchase? (or asked to try out the storecard… 10% off anything you buy with it today!) 
Seriously though, I’ve had upsells on my main products for years and would guess they’ve made me tens of thousands of dollars in extra profit.
