If you live outside the US but want to order from a store that only ships to US addresses, web service Bongo International will provide you with a US address from which you can forward your package overseas.
Sometimes you can only find what you need at an American website, like eBay, Amazon or Best Buy, but they won't ship internationally. After reading technology website Digital Inspiration's guide to shopping at American websites, I went hunting for the best parcel forwarding service around, and found Boingo International to be the most popular one.
Bongo International provides you with a US address to which you can ship items from online stores. Bongo will then forward those items on to you, either immediately or all bundled as one shipment, which is particularly useful for saving money and shopping at multiple stores. You can pay shipping on a per-use basis, though you can also get discounted rates through a $US15/month subscription.
