I wanted to keep costs down! There are no payment gateways which are independent of banks and which take payments in South African Rand. If I wanted to take Rands I would have to set up an business merchant account with a (South African) bank, produce all sorts of paperwork yadda yadda and pay much more in fees. In the end, I would have to charge serious fees and could only then have reps advertising, which defeats the purpose.
