USPS seems to be the most reasonable. I will ship Priority Mail in the US. This system allows me to enter only one price for shipping. It you are ordering one item, e-mail me and we will adjust the price.
International orders will go by USPS Priority Airmail and take about a week. E-mail me for a Postage Quote. Include you country and postal code.
I attempt to ship the day after receiving your order. If there is an excessive delay, I will let you know.
