Yes, Skoosh.com is NOT a valid site for BRGs as it uses prepaid vouchers that you must print off and bring to the hotel. This goes against Triprewards BRG Terms and conditions.

If you are wondering more about Skoosh, there is lengthy talk about it and why exactly it will not work for you, on my blog. Also, there is quite a few articles about how to form proper claims and ensure they get approved each time.
