I have started listing a few plants on ETSY, but as you stated, there is less exposure there. I don't know about having to deal with "rules violations" with ETSY. I sure have had (bad) experiences with eBay though. I too don't really use FB to sell anything. I just don't have the time to list on multiple venues. Just keeping up with what I have to do takes an incredible amount of time. That's the problem being a hobbyist grower with one employee...............me.
