Those large flat rate boxes (which are smaller than regular priority large boxes) wouldn't have held all those daylilies Mona :nodding:, he would of had to send 2 boxes. Yes it would have saved a little on his end, but that means that's an extra box to keep up with to make sure the order doesn't get messed up (IMHO). I know when I ordered from them fall 2010 they shipped UPS.
I just shipped out some large flat rate boxes with 23-25 fans (some SF,DF,and 3-5F clumps) in them and some of them were bulging at the seams.
Here's a difference of opinion on what to charge for shipping costs. Some people think of it as the actual shipping cost, but others see it as shipping and handling or shipping and processing. Think about all the things you see on tv to buy or wherever, you GET THE SECOND ONE FREE but you have to pay the S&H for the free one also. This is to help recoup any labor costs, advertising, and such.
Daylilies don't dig, divide, wash, and box up themselves so the extra shipping is kind of paying for your time doing this.
