I've ordered some manga books and asked them to be shipped to me via Media Mail with Delivery Confirmation.

Now they have gotten back to me saying their post office won't allow them to be shipped via Media Mail (they live in Sarasota, FL).

Is it possible the post office there won't allow this?  I have had many, many manga books shipped to me via Media Mail?

My PO told me audiobooks couldn't be sent MM. And I get them on ebay MM all the time.

These aren't audio books, they are paperback books.  Japanese graphic novels.

Do your manga books have any advertising in them? That's the only reason that they would not be allowed to go MM, well, and if the are under 8 pages, but I'd think they would be more than that.

I know I was just pointing out that the postal workers are not always correct. 

*Sigh*

I have tremendous appreciation and affection for the post office, my local PO in particular. But for whatever reason, clerks don't always know PO rules. Whether it's willful ignorance, poor training, whatever.

Here's the link to the entry in the Post Office's own manual describing Media Mail: http://pe.usps.gov/search/jsp/search/vv_docread.jsp?k2dockey=http%3A%2F%2Fpe.usps.com%2Ftext%2Fdmm300%2F173.htm%40PE_DMM300_HTML_5&serverSpec=56.0.145.56:9920&QueryParser=Simple&querytext=%28media%3CAND%3Email%29&dtype=2#hit0

Have the potential mailer package the books, take them to the PO, try to mail them. If there's a problem, ask the clerk to call the PostMaster over to show the actual rule where it says the books can't be sent Media Mail.

PS: Same situation for audiobooks

ETA: contract stations (like at the grocery, hardware store, etc) don't always offer all mail services. Post Office locations on college campuses offer limited services too, sometimes. If that's the problem, try mailing from a regular Postal Station.
