I agree that when someone orders off of eBay, and that experience is poor, they need to leave feed-back. Also, in my opinion, eBay cares far more for the customer than it does for the seller, so if you lodge a complaint with them, you'll probably get results. Take plenty of photos too. Nothing beats "visual".
No, I put root-balls in baggies, along with moist sphagnum moss, but that's it. Of course, I do use air pillows, bubble wrap, and Styrofoam peanuts, but those are only for shock absorption. I use lots of newspaper, wrapping and shredded.
