I just saw a Harvey Norman TV ad for MS Office 2010 (single user licence I think) with bonus $50 Rebel Sport voucher for $128. Comparable to the recent DSE promotion if you don't need the power board (and possibly the extra licences).
As I can't find any mention of it online, and I'm not entirely sure of how much a bargain it is, I figured the forums may be more appropriate for this.
Please let me know if this is not the case.
