I have sold some books on half.com and I need to ship them soon. What is the best way to pack and ship them? Boxes? Bubble mailers?
To the 2nd poster: what if it rains? The books would get wet, wouldn't they?

To both: I am sending 1-2 books at a time.

Also, I was thinking more along the lines of bubble mailers because they're inexpensive and come in many sizes.

If it's one at a time, I wrap them in brown paper grocery bags and tape them up. If it's several, a box will do.
