Yes, we are happy to combine shipping for multiple pieces. Our pieces have different weights, however, and that makes it a bit challenging to combine shipping as you are ordering, but you will only pay the actual combined shipping cost plus a $1.00 handling & material fee. We will refund any overages as soon as we create the shipping label (thst's the point when we know the actual price for shipping).
