Help~! I have a customer waiting! Combined Shipping Invoice How do I prepare one?

[Anonymous]

I went to the screen to send the invoice and I filled it in and picked the lowest shipping, but the amount doesn't seem to change on the invoice?  Or is it that when I picked the 2 items from the sold screen, and it took me to the invoice screen IS THAT the combined shipping price?  Shouldn't it be cheaper? I thought the combined shipping was an incentive to buy more than one item so it would give a discounted shipping price. But the 2 items he bought one shipped at 5.50 and the other at 4.50 and the total on the invoice is 11.96? I tried to apply a discount, but it would let me. The 2 items he purchased together with packaging weigh 4.106 oz. However separately they are listed at 3 oz each.

If the buyer hasn't paid, you click on Send Invoice on one of the items.  Both items will show up for you to select the items to be included.  The next screen shows the totals and allows you to adjust the shipping option and cost before you send the invoice to the buyer.

How did you try to apply a discount?  All you need to do is just clear and type in the amount you want to charge.
