We are happy to ship items together to save you postage.  As many of our items are different shapes, sizes and weights, we cannot use a standardized "ship together" combined shipping tool that offers.  When you purchase multiple items (at the same time) we pack them, weigh them, and then charge you the actual postage.  If you have already paid, we will refund any difference between what you paid for shipping and what it cost us to ship them. 

Questions welcome!
