Trying to figure out what the deal is with this box. It doesn't say "flat rate" like the others. It definitely isn't in the Ebay drop-down for shipping and isn't a small or medium flat rate box. What the heck is it, exactly? Is this just a box that the post office gives where the price is determined by weight just the same as if you packed your own box and weighed it? That doesn't make much sense, however.
Has anyone used these before? What option do I use to print the label from Ebay?
