I was just reading a thread on how you can print a parcel post shipping label from Pay-pal. That would be great and save lots of money. Ok, here's 2 questions. One is, can I still use my free priority mail boxes when shipping parcel post and printing out a parcel post label. I know I've received things UPS where suppliers have used these free boxes but wondering if I can use Parcel Post printed at home shipping label with these boxes.? Two is, when I check for going on line and sceduling a carrier pick-up through the USPS site, it says you must have at least one priority mail or overnight package with your parcel post in order to schedule a pick-up. Is there a why of getting around this? Does the pay-pal site have where you can schedule a pick-up for parcel post? This would be so cool it I could make this work. Save my customers alot on shipping. Thanks!
