Order didn’t combine shipping for buyer

[sharonspdc]

I am using the new payment system. My first multi item order was received this morning (she purchased two seperate items) and the buyer said she couldn't get the postage to combine at checkout and got charged twice for postage. Is this an issue under the new payment system?

did she use the cart & then request combined postage?

No I have the box ticked in the listing, so it suppose to combine automatically 

Combined postage discounts

Offering postage discounts to buyers is a great way of encouraging them to buy multiple items from you. When you offer combined postage discounts, buyers see the message "Save on postage" in your listing
