I just got your book the other day. I am currently selling fulltime on Ebay and always try to find the most cost effective way to ship my items. I see you are using the flat rate priority mail envelopes to ship your books at $4.95. It is much cheaper to ship via media mail USPS - Media Mail Prices. Also my address was handwritten, I use a Brother Ql-570 thermal label printer which is around $50.00 on amazon. It is great and saves a ton of time with shipping. I hope you find this useful. Thank you for the book and for your forum.
