During my years overseas one of the biggest frustrations is having no access to affordable supplements and products along with huge shipping fees. When I discovered iHerb, I felt like I'd found a cache of gold! Now about once a month I order supplements for my own health, gluten free products for one of my children, and herbals for the whole family. iHerb DOES ship to Thailand. $4.00 shipping for up to 4lb in weight. Keep the maximum spent at $50 so the package doesn't take a detour through customs. Expect to pay a 7 or 9 baht fee to the post office when it's delivered.
