I love WordPress. It’s too easy to use, too effective at what it does, and it’s just the right price for my pocketbook. WordPress is “software for the rest of us” – cheap (it’s actually FREE, but we donate, right?), easy to use, and it’s good.
But if you want to use WordPress as a platform for selling digital products, you need to be able to support PayPal and ClickBank and protect your digital property from being accessed by folks who’ve chosen not to pay first.
You also needed something that made it easy to market products as an affiliate (to sell other people’s products that compliment yours) and effortlessly cloak my affiliate links.
