There is a separate number for employee purchases (not the MAC pro #)...but you're just getting a Lauder discount right? It may be different than the MAC employee discount number, I don't know it offhand, but it should be in your paperwork.
eyeshadow pans are $10.50 and blush pans i believe are $14.50. if you are an industry professional, you can order them through the pro #. if you are a MAC employee, you can get them through the customer service 800#.
