A few issues though.
1)If the parcel is sent to them via US Postal Service the US gov then requires you to prove your ID, this can be a challenge (they didnt like my SA ID because that didnt expire. They accepted my passport but then needed some other doc as well, they didnt like my drivers licence because that didnt have me name spelt in full, they didnt like my council bill because that had the same problem, it turned out none of my other documents had my name spelt out in full...............

2) They ship via Fedex and claim very good rates but its still quite pricey shipping via Fedex to SA. But they are fast and efficient.
