Look at http://www.bhphotovideo.com/ there are plenty of us who have imported from them and they are much cheaper than local.
Just remember if you import a camera all customs duties VAT comes to around 21 - 22 %
On lenses is only 14%
*guys please let me know if I am wrong on this
Aparently cameras are duty free though there's a clearance fee and VAT that need to be paid.
Had a look and yes. My current 1000D's charger is autoswitching. Im definitely comparing prices between local and US and will certainly not import unless it's really worth the savings.
Look on the SARS website, but it's one of the worse websites out there, not easy to find stuff.
I have imported cameras & lenses recently, maybe I can quote the codes for you tonight, I'll try to remember.
Note : They sell USA flat pin -> Euro round pin adapters for R20 at Mica, but quite poor quality. B&H sell better ones for USD4.
Also some brands are overpriced in SA. Particularly Sony. So there you might score.
Look at this thread. It has all the calculations you need to work out what needs to be paid.
In effect there are 3 amounts that get paid. Duties, Excise and VAT. On lenses the only amount payable is VAT... but the VAT is payable on the (Cost + 10%). On Cameras there is Duties to be paid as well. Check the thread its more detailed.
Always do your calcs. Depending on what you importing you can save R1000's. On the mainstream cams p&s and DSLR its not worth it. On your higher end p&s there is some saving. Also some brands are overpriced in SA. Particularly Sony. So there you might score.
