The only opinion I can give, being a newb to JV, is from the client end. I have no idea from the conversion end. These exit popups annoy me so much I'd like to hunt down the person using them and then hunt down his/her parents. *laughs* Seriously, I find them highly annoying and if I go to a site that uses them I would seriously consider not buying a product if they were used.

While I'm new to IM from the JV side I'm not new to selling on the web. One of the things I've learned over the last 10 years is you make it as easy as possible for someone to purchase a product. You make their experience as pleasant as possible at the same time. Imagine if you were in a store and as you were leaving a sales clerk rushed up to you and locked the door saying, "Wouldn't you really like to look at....." or, "If you stay a little longer we can give you an additional 5% off!" I'd never go back to that store and I think many people would feel the same way.
