I just purchased a shipping label and found that the shipping prices has gone up again. So for anyone buying postage, just a heads up. 

The new prices are in affect tomorrow: http://www.stamps.com/usps/postage-rate-increase/ and https://www.usps.com/new-prices.htm

The updated information is in the Whats New (upper right corner) and Help Center sections on PBS http://www.paperbackswap.com/misc/whats_new.php#new_postal_rates_effective_jan_27__2013

So I went to mail a book that I printed the label for this morning and the post office wanted to charge me an additional $.90 to use the confirmation number issued to me by PBS. The new fees include confirmation numbers on first class and media mail so I paid PBS  for confirmation numbers to get my credits quickly but now I am going to have to wait. I sent an email asking PBS how this is going to work so I will update when I get more info.

If someone has info on this please let me know.

thanks

Jane
