Affiliate Marketing Secrets

What are the pros and cons besides the pricing of $99 per month vs. free? Does Zen Cart have support? I feel I need phone support which is an additional fee with 1Shopping Cart. I will be selling downloadable info products. I also need to track affiliates and pay their commissions. The autoresponder is also important. I am concerned about starting with one and losing opted in prospects if I have to switch over. Does anyone have experience with both?

I used to create this webcomic called “Cheap ZEN Soup” a couple of years ago, but it never really took off – and then I got caught up in my freelance writing duties and I stopped having time for the daily webstrip experiment routine.
Looking back in perspective, sometimes I cannot help but wonder… should I keep working on this experiment? Would anybody possibly get into it? Would there be an audience… who knows? Is that even important (ok I’m going into rhetorics as we speak)?

Let me know what you think. It’s kind of like a meta-webcomic with a twist. It you like stuff like Scott McCould’s meta-comics, or niche manga like Bakuman, G Senjou Heaven’s Door, and Even a Monkey can Draw Manga, maybe even old-school cartoonists like Harvey Pekar or Robert Crumb… maybe you’ll enjoy this as well.
