What's the minimum and maximimum amount I can buy prepaid electricity for?

The minimum purchase amount for prepaid electricity on Spot is R10.00. 

The maximum purchase amount is capped at R1000.00. But there's no limit to the number of times you can buy electricity. For example,  If you'd like to make a R2000.00 prepaid electricity payment, all you'd need to do is make 2 payments of R1000.00.
