I am really confused over all this, to me its a big mess. I was shipping last night and I was using a priority t-vek bag and I had to put in the measurements. This is insane! If using the priority boxes from USPS, why the ---- measurements?
Also, I am sure we don't always know the size of box we are going to use BEFORE shipping, especially if the buyer purchases more than (1) item. Maybe I am making it harder on myself, but I am very confused right now. I think the USPS has been smokin' something funny.
Any good advice out there?
