I will explain as best i can my problem.
I sell used postage stamps
Some of my customers buy 50 or 60 items
I send an invoice which is a maximum of 40 items
I adjust postage as I offer combined postage
When my customer goes to pay they are asked to pay postage on each of the 40 items
This is an example from a customer today.
I have the same problem again.
When I tried to pay your invoice I got total items (67) $17.20
Postage $77.00
Can anyone help me with what is happening
Cheers
Dave
