What happens when I purchase a backorder along with an in-stock item?

You can choose your preferred delivery modes for in-stock item(s) and backorder item(s) separately.
A gentle note that we are unable to provide a combined delivery/shipping of in-stock item(s) and backorder item(s). 

Complimentary standard courier will be provided for local orders (consisting of either in-stocks only or backorders only) above S$80.
