International delivery will vary based upon the shipping method chosen. Carrier and customs delays are not within our control. The quoted shipping cost is for delivery to the destination country only - the receiver of the package assumes all obligations to pay any applicable duties, fees, or taxes subjected to the products purchased.
We offer everything from first class mail to overnight delivery and it is based upon the weight of the order, so shipping will vary. First class mail for 4 batteries would be around $3.xx
