New question..see below...did not want to clutter up the board! :-)

This has been the USPS rule since July 30, 2007. Over 13 ounces, stamped parcels much be taken to a retail postal counter.

Here's a portion of the  official announcement:

WASHINGTON, DC — A new Postal Service rule goes into effect next week for packages and envelopes that weigh more than 13 ounces, if they’re being mailed with only stamps as postage at a location other than a Post Office retail service counter.

Starting Monday, July 30, customers can use one of several convenient online postage applications — available 24/7 — or an Automated Postal Center, if they wish to mail items that weigh more than 13 ounces in Postal Service collection boxes or Post Office lobby mail slots; or if they wish to leave the items for pickup by their letter carriers. Online postage applications include the Postal Service’s Click-N-Ship service on usps.com and PC Postage from an authorized USPS vendor.

PBS postage is fine to use. (And paypal or stamps.com)

new question ^^

UPS website click n ship says I can only mail with priority...this is not a problem on PBS, as their system lets me ship with media mail, however it is a problem with book mooch. Is their anyway to ship using ups (or another free site) and print postage using media mail rates?

Alison, it's ok to make another thread for a different question. It's not cluttering up the board and others may have an interest in the original topic.

You can use paypay to send media mail. Bookmark this link because they hide it well.

Paypal postage link

You'll find that this is the USPS link and has nothing to do with UPS :D

Thanks so much again ^_^

Sorry about all the questions...as you can probably tell, Im new to the online book swap community. I absolutely love it  though...what a wonderful idea and site  :-)

No need to apologize for asking questions, Alison! There's plenty of people at PBS who will be glad to help you out!

I was going to suggest the "mail to a friend" option too.  Just make sure if you post the book to your PBS shelf in order to do this, that it isn't a WL book first.  I hate going to the PO and to me the charge for the printed postage is worth the cost.  Normally I use stamps on my BOB requests since I only do them for 1 or 2 books at time. But I had a larger book to mail that was 14oz. I reposted it to my shelf, it had been removed when I accepted the BOB.  It only took a few seconds to repost it and then I immediately hit the mail to a friend option.  It shows up in your Enroute to Me books and your Books I've mailed tabs.  You just mark it received when the other person gets it.  Very simple.
