I collect and sell rare used books and my business is starting to thrive. I use private carriers (5-letter, etc) after much frustration with USPS. How does one go about shipping from home via a fdex account so as to avoid long lines/hassles at the shipping office? I know you sign up online and can order supplies - my question is: Do you have to purchase a label-printer so you can print your own shipping labels? Has anyone used this method and do you think it is a good alternative to shipping in person at the local MailboxesRUs ?? Seems like a label printer would cost alot of money. Thanks!!!!
