It certainly would have been helpful and saved a waste of my time if the survey had stated at the beginning what the proposed box sizes with postage charges are. They may be great for some sellers shipping clothing, dvds, but for the most part would be useless for me. Also, how can one say , yes, I would use it without knowing the cost first? If CP is trying to do what the USPS has done, there needs to be an inclusion of a small box of about 8" x 8" x 8" - all they are asking about are flats.
