I sold 4 books in a series to a buyer in Mexico. The box weighs just a hair over 7 lbs. He now wants to buy 11 more of the books [I obtained a stack of them].
I would be nervous about mailing anything that heavy even within the US, let alone to Mexico. He wants a quote for ground shipping.
Would you, in this case, set a limit on the number of books you would mail in a carton? Take them to a packaging center and have them package the books securely [do those places give a guarantee?]? Just do your best and hope for the best?

Add at least one piece with weight
Note you can usually do one parcel with all books in it. So number of pieces is 1 with gross rate.
