When you order mutiplies from one person and you mark the books received, Do you fill in all the info amount of postage, shipping date, etc. on all books or just one?

Just fill it in once.

I do enter it for all of them and then in the feedback box I indicate, 1 of 3, 2 of 3, etc. depending on how many books were packed together.

I just fill it in once, then for the others I write "part of a multi-book order" in the comment box.

I fill in everything except the postage price part, cause if they send you 3 or 4 books it's going to be way heavier than just one.

Like Mary, I fill everything in except the postage if I've ordered a few. If I'm in a rush and there are more than 4 or they used dc, I just do one -

I think I entered them in each separately. I never thought of just saying "part of multiple order." That makes more sense than the sender paying $2.38 to ship each book when they paid it to ship 2 at once.

I don't fill it out at all unless there was a problem with the mailing date or packaging. (For example, if they marked the book mailed and when it arrives the metered postage sticker says it was mailed 2 weeks later than they said.)

I fill it out for each book but I don't put in the postage cost more than once.  I do indicate it was part of a multi book order.

ETA - I only put that I received all books in the PM to sender once.
