I sometimes will buy two of the same book (either I forget when I'm at the store I have it, or someone gives it to me etc). I would like to list both books, however the system will only take one. How can I post two of the same exact book?

Thank you!

The short answer, you can't.  I think it is set up that way to keep people from accidentally posting the same book twice when they only have one. 

Ahhh I see. Thank you! 

You should be able to post the second book though if the first gets requested and sent to another member right?

I think when you mark the first one mailed, then you can post the second one.

Thank you!

There is a built in way that if you order two of the same book, then you can post two copies.  Otherwise the safety kicks in to only let us post one copy of one ISBN.
