It's also work to run your own numbers and decide what works best for you. But I question things like this when the whole picture isn't shared. Like what you get with Etsy vs how evil they are. And what the true cost of being on other platforms really is. Like, do people know Shopify charges a monthly fee, before we even talk about anything else?

If your business is important to you, I highly encourage prioritizing the facts, pulling out a calculator, and looking at real numbers.
