Hello 'akdesignstudio',
Your seller has her listings set up for Immediate Payment Required. You can contact the seller
to sort it out, or if you are impatient and want to complete an order swiftly, you can always
go to www.ebay.co.uk or www.ebay.com and sign in, then add the items to a shopping cart.
When you are ready to pay, all those items in a same currency can be paid at one time, even
if they are from different sellers.
If you are buying multiples from a seller who offers a 'combined' shipping discount, however, be sure
the discount shows at checkout if you go that route. Otherwise you will have to wait for an invoice
from the seller, either by using the Ask a question link or the Request Total button.
