There is an 'intranet' with that info, for company personals! if you know someone, then they might share it with you. Most of this info in available through 'myapps' application just in case you are with QR already!
hope it helps. even though they might list the discounts, I have found better deals else where! except for money transfer, insurance and bank discounts, I have not benefited from any other deals, including car rentals or purchases. You are better off waiting for a special and then you will get the deals!
Good Luck!
