Shopify lets you easily put together an online shop and get paid for your stuff. The sites look nice and they have a good reputation in the software development community. They even have help for online marketing.
The plans start at $29 dollars a month and they take a 2% commission. Not sure if that's good or not. For $59 per month you get some more features and they take a 1% commission.
I'm a software developer (for the Montana state government, not Shopify) and just getting started with smithing. So my skills lean way more toward sitting in a chair and typing.
