I personally mainly run on Facebook Marketplace and have a bit of experience on both eBay and Shopify. I personally believe Facebook and Facebook shops have an enormous upside, and I know people who are consistently pulling $10-20k a month with teams of VAs, and it is relatively simple to get started. eBay is always solid, and I know that a lot of people go crazy with POD on platforms like Etsy and Redbubble. Just curious what yall's favorites are. Cheers!
