Yes you can dude, but it works on a month-to-month basis, i.e. debit order. It's R99 a month for up to 3 games per month, one at a time. After 6 months you can switch to the unlimited option which is R199 p/m with unlimited games a month, but still only one at a time.
The titles they have available will vary from branch to branch. The one in Bloem has most of the new titles on X360 and PS3, e.g. Mass Effect 2, Just Cause 2, God of War III, Aliens vs Predator, Bioshock 2, etc.
