R4000 is quite a decent price for the set, that is, if you're into JRPGs such as FF13.
Personally I would probably take it immediately.
The extra 130BG and the R600-700ish game sound like a fair reward for R1000 extra, (If you think of the Makro special last week) especially considering that games are likely to use more and more space (As seen by FF13, which takes up 18.4GB).
