Are we allowed to post single volume comic books in the Book Bazaar?  I know we can't in the normal system, but was curious if we could in the Bazaar.  I got two 17 year old X-men that I have no use for.  They're in good shape, worn is all no tears.  Thanks

Only if they are offered free with a request.  Also, you can't send them media mail, so you may want to check out the postage rates first.

Under General Rules in the Book Bazaar:
(3) No selling books for anything but credits, and no offering anything but books for credits. Freebies/incentives can be "non-swappable" items, but remember that non-Media-Mail eligible items CANNOT be sent using Media Mail postal rate. For example, DVDs and VHS tapes and magazines and pamphlets/booklets without ISBNs are all NOT permitted to be posted at PBS; they can all be offered as freebies/incentives, though. But if the freebie/incentive items contain advertising (ie, magazines or booklets bought at a supermarket checkout stand), or are not Media items (anything but books, CDs, DVDs, VHS tapes) they can't be sent Media Mail, so the whole package will have to go by another shipping rate. DVDs/VHS tapes/CDs can be sent using Media Mail postal rate.

I hope this helps. 

I was hoping so!!!  I was actually going to offer them as freebies with a purchase so thank you for your help!

Some comic books and graphic novels have ads inside.  Some don't.  If the ads are just for other comic books or graphic novels put out by the same company, then it can be considered media mail.
