Both domestic and international is by USPS first class mail. Domestic shipping charges are $.70 postage + $5.90 insurance + $1.04 eBay fees + 36c shipping supplies = $8.
If you purchase multiple items and you wait for me to send you an invoice then I am pleased to combine shipping. If you do not wait for me to send you an invoice then you will pay more for shipping.
