I'm noticing some discrepancies when printing the shipping label.  To mail a paperback weighing 6.2 oz (with no DC), the "Customize Your PBS Wrapper" page is telling me that the cost to mail this book will be $2.15.  However, when I click on the "Print Wrapper" button on that page and open the .pdf file to print the label, it is telling me that the "Suggested First Class Rate" is $1.98.  And finally, several of the paperbacks I've recently received here at my home were shipped for $2.13.  I'm budget conscious and now confused.  Which is correct?

$1.98 and $2.15 are the first class rates for 6 and 7 oz. packages/books.  The $2.13 is the media mail rate for <1 lb. books and other "media" items.    First class is faster, of course----unfortunately, the estimates that PBS prints are very frequestly wrong for what the final weight of the packaged book might be---sometimes by a great deal.  I strongly recommend a postal scale in oz. at least up to 1 lb.  I weigh all (!!!) of my packages and calculate the postage myself----I don't see any other way to do it without paying too much, losing out on first class rates, which are always faster and often (for lighter books) cheaper, or paying too little and having packages arrive "postage-due" which creates "PO'ed" recipients, and sometimes returned packages for additional postage.  I would go to  a office supply place and buy a good scale in oz. at least up to 1 lb., and print out the first-class package and media mail tables from the USPS websites and calculate your own poatage----self-defense at least!!

Remember that books/packages between 13 oz. and 1 lb., if you are using stamps for postage, must be handed across the counter and not thrown in a "blue box."

Sorry for the triple post---computer put the same thing in 3 times! 

My computer is acting up and put this in 3 times!

Thanks Winston!  That clears it up perfectly for me!  Much appreciative for your reply.

My PO tells me that if the book weighs 6.1oz, I must pay the 7oz rate - 2.15 for first class. Only if the book is under 6oz am I allowed to send it for 1.98. They have even been picky when the book weighs 5.90 something ounces and asked for the 6 oz. and over cost. I guess it must vary from PO to PO.    M'ann

Your Post Office is correct: "7 oz" means up to and including 7.00 oz.  It is true that a 6.1 oz book should cost $2.15 to send FC.
