always mail your packages promptly

I sold a book on, and was supposed to mail it by last Tuesday by Media Mail.  I mailed it today, and paid far more for the shipping than the buyer did, to make up for how late I shipped it.  I paid $12.  I just checked, and I sold the book for $16.  I guess it’s still a $4 profit.  But still, lesson learned: always mail your packages promptly!
