Hi Yaamba, that can be quite frustrating.
Couple of options, firstly you could network with a US member here and offer an incentive for them to forward your items to you, using their address for delivery.
Secondly, you can use mail forwarding companies to provide you with a US address, however when it comes to selling products these types of services are usually too expensive to utilize.
My suggestion, connect with a US member here on the forum and see if you can work out a deal that is suitable for both.
