michelle, I just looked at a couple of your listings and they are marked "immediate payment required"  You cannot give combined postage for immediate payment items.

I have it set up...thanks for jogging my memory to go and check.
I have no idea what the problem is but this is EBay and I have given up second guessing what is happening.

I have just put two of your books in the cart (the ones with postage costs, obviously) and I am getting the "request total" button. Ask the buyer if they are using a phone.
