If you are able to not pay right after purchase, please wait for us to send you and invoice as we look at both USPS and FedEx for pricing, as here lately with fuel prices, the rates get adjusted weekly it seems, this is for single and combined shipping. We do our best to find you the best rates and at times will change your shipping to either of the 2 shippers we use (sorry, we do not use UPS due to issues we have had).
For Combined shipping, if you pay for each item separately, we will combine them during shipping and refund over-payments minus eBay and shipping cost.
