*** Amended 5-2-2016: Please view the more up-to-date blog post Ordering From Amazon in South Africa, Take Two ***
Okay, I'm exaggerating again, lest a South African reader might be offended. But the big, big problem about living here is that there is no Amazon.co.za. There are other companies that claim to deliver the same services, like Kalahari.com, but that one is a far cry from the real deal. I've given up looking for stuff there. Then there are other websites advertising their competence in sourcing any actual Amazon.com product for you, like wantitall.co.za or have2have.co.za. I have to admit I haven't tried any of them, but I have my doubts.
The latter, in the past, has offered free "Super Saver Delivery on Selected Items to Selected International Destinations," so keep your eyes open for any similar recurring deals, especially around holiday time.
The one Amazon product you should absolutely invest in while living in South Africa is a Kindle, because books are really expensive here. Our kids, as of this Christmas, now all have their own Kindles, and the amount of reading being done has at least tripled (okay, not really an argument for saving money, but when it comes to reading, I am being irrational, as Noisette will affirm).
I'm not sure whether the UK or the USA makes more sense in terms of Amazon deliveries and Kindle book purchases. Check out their international shipping pages at Amazon.co.uk International Deliveries and Amazon.com Shipping Rates to Africa. You'll just have to look at both of them and decide. The one thing that speaks for the UK is that in case you buy any electronics, they will have the right voltage and maybe a plug that fits. I'm saying maybe because it seems like no matter what, we have about fifteen plug adapters coming out of any single outlet in our house.
