We will combine shipping. So the more you buy the better the average cost. If you are buying on an iPhone or the like generally the apps only let you buy AND pay in which case we will refund the extra. But with a lap top or desk top computer commit to buy and then wait for me to send the combine invoice. For  books the incremental cost is $1.50 each.  We ae unable to send an invoice if the items are merely in your cart.
