I'd like to get some opinions about the use of priority flat rate boxes... All of the live plants I've received on the forum so far have been the 4.95 flat rate boxes, but I've heard that first class is exactly the same except for shipping confirmation. Is this true to you? for me, box excluded, it would cost about a third the cost to ship most of my plants with normal first class than using a flat rate box. And for plants that have a worth of 4-5 bucks, the latter doesn't really make sense.
What shipping method do you use, and why? I've never had to ship delicate plants before so I've always just used first class and they've arrived fine.
