We are happy to ship items together to save you postage. However, since our items are not uniform in size or weight, we are unable to use the combined shipping tool. Therefore, when you purchase multiple items from us (at the same time), we will pack them, weigh them and charge you the actual postage. If you have already paid, we will refund the difference between what you paid for shipping and what it actually cost us to send them to you. Questions welcome!
