I've sold online before (though not as a candlemaker--I did sell scented products and bath/body products that I made, and other items), both part time and full time. My suggestion to anyone wanting to sell online is to test the waters first. You can sell from a blog, and a blog is totally free. You can open a free store via Squareup dot com. That is a fairly new service they offer, as they used to only process credit card payments, and initially they only did that via a smartphone app. You can also sell via Etsy, of course, and only pay their fees; their fees do add up over time, but it may be a good option for you if you're just starting out or not doing a large volume of products/sales. You can also set up a Facebook page for your business and sell that way. Many people do that now since it's free. FB makes it harder for posts by Pages to get seen anymore (unless you buy ads, that is), but it's still a good way to get started if you have a tight budget and can't afford a full eCommerce store. Once you've established your store, your products, and a strong customer base and sales, then you can switch to a fully hosted eCommerce store that will meet your needs, and your budget.
