Hotel Aggregator

From Brandon McQueen (google is unaware it seems), comes the pointer to an aggregator of hotel room reservations (from Australia) for comparison shopping with upto 10% rebate for university people. I haven't used their service; if someone has any experience with them, please let me know. Btw, one should also understand the legal aspects of getting rebate on a travel that is reimbursed through one's employer, and how to discount them on reimbursement forms.
