I have a request for two books, both by Jodi Picolt so the books are pretty think. Does anyone have a good way to send these in the same order?

I start with a plastic inner wrap and then I usually take a large (heavy manila) mailing envelope and open it by cutting off the flap and bottom closed end and turn it into a large sheet of paper. Then I use that to wrap the books just like a package. I use the single page address label and make sure all the folds on the package are well taped. I've also used bubble mailers opened up the same way as it's easier for me to fold down ends then to try to conform the shape of an envelope to a book block.

Linda, I never thought of that before! I will have to keep that in mind! Or use it right now because I found an old amazon gift box lying around the fits both books perfectly, but I have no idea if media mail can be sent in a box. I suppose that is a stupid question, but I don't want it returned to me or the other person charged extra postage. Do you know off hand?

Yes, Media Mail is fine in a box. As your box will be over 13 oz, you need to use printed postage or go to the post office.

I keep the small Amazon boxes on hand for thick hardcovers, audiobooks and bulk orders. I'll put plastic bags around it to protect the book from bouncing around in the box.

I wrap in plastic, then I use a thick paper bag (like the grocery bags from Whole Foods), double it over, wrap, tape corners securely, and mail. Or I use bubble envelopes. I only use boxes for larger numbers of multiples, because they add a lot of weight, and they don't fit into my mailbox.

I do use boxes once in a while (I try & save all the small ones I get and keep them flat folded), sometimes it's better when there are books that are different sizes & the box makes it easier or if there are 4 or more books to be shipped & wrapping them in paper is more difficult. But it also depends on if the added weight of the box & any padding inside is enough to bump it to the next media mail price increment, if so I might not do it if I can manage to create a tightly wrapped package.

DH has a home office & we use printed postage using an endicia account & a dymo label maker. It doesn't do 'media mail' per se, but postage is interchangeable and the right combination of first class increments will equal the media mail rates.

Please, if you use anything with ink on the inside, please use a layer of plastic or paper. The inks can bleed on to the covers.

My favorite wrapping is old paper maps. Thin weight, but tough enough to hold up to folding.

For two books, I wrap them together in plastic wrap and then stick them in a plastic mailer and tape it tight around both books.

For three books, I usually find a small box that works.

Depending on the size and wrapping material I have on hand.  Small boxes can be handy for multiples, or if not too big I just wrap in plastic than take a couple turns around the books to secure them into a firm 'brick' and wrap with sturdy paper.  This works for 2 or 3 pocketbooks, but for hardcovers I prefer a box b/c USPS often bends the corners of unprotected hardcovers.

I've sent up to 10 books (paperbacks) together in a paper package.

The trick is

1. wrap the books in plastic (plastic bag or whatever).
2. Tape around the plastic in all three directions, tightly, making a "book brick". Your book brick should be a solid block, not a wiggly pile. Sometimes, depending on the size of the books, I make 2 bricks and then tape the bricks together.
3. Wrap in paper or other wrapper, with appropriate tape.

As long as you make a solid block, the books will be fine.

I have used the same "brick" method as Sara and it makes putting on the outer wrapping much easier. 

Small boxes as stated by others are great for multiples.
