Selling stuff online has become the new "side business" of many Internet users, whether it's used clothes, vintage computer items, custom-made gadgets, or homemade cookies. There are numerous venues to do this without having to expend any brainpower (eBay still being the go-to source) but there are downsides to using those services—namely, there are so many people using them to sell items of questionable quality that it's easy to get dismissed as "yet another eBay seller."
But making your own e-commerce site is a huge pain and easy to screw up, isn't it? Well, yes and no. To build an entire system from the ground up might require more time and resources than you currently have, but you can easily fake it by creating a site to hawk your wares and by using PayPal as a payment processing back-end—and your buyers don't even have to have a PayPal account to buy from you. Here's a simple tutorial for setting up your own site to sell stuff with the help of PayPal.
