In genera, my MMPs are less than 8oz after packaging.  In fact, PBS shoots out a First Class wrapper.  However, they are usually over 3/4".  I would think this is not within USPS guidelines of 3/4" thickness or less.  Even if the book size input on PBS is 1" it shoots out that First Class wrapper.  Anyone else worried about the 3/4" rule?

At 8 oz it should be media mail anyway but if you are printing postage you can change the weight of the book to make it 8 or more oz that way its not first class and the rule doesnt apply. Anything under 1 lb will show up as $2.13 in postage for media.

I've never given any "3/4" rule" a thought when deciding to mail a book - I'd thought that if you want to pay the FC rate it doesn't matter?

PBS is giving you the First Class Parcel rate. This is the correct rate for packages that are over 3/4" thick, so it sounds like you have nothing to worry about.

If your package is less than 3/4" thick, then you have to pad it a little bit if you're using printable postage with delivery confirmation or delivery confirmation alone. Any item with DC on it has to be at least 3/4" thick.

Thanks ladies.  I think I'm remembering now:)
