Each code is unique to the receiver and can only be used once. Some people received emails like mine while others received 20% off everything. It seems to be random but also cruel since I didn't get the 20% off everything coupon. Some people didn't receive a coupon at all but had luck contacting customer service for one via email. Remember this can be used with any rewards you have saved up. Now is a good time as this sale, which includes Prestige items only comes around once or twice a year. 

Use the code above to get 20% off everything even sale items. I also received an email today for 25% off and free shipping on $49+. Expires 10/25. The code is SAVENOW. Not sure if this one excludes sale items but I'd say try both and see which one saves more. Remember CVS offers 100% money back guarantee on beauty purchases you are unhappy with. 

Walgreen's and Drugstore.com are also both offering savings on plenty of beauty items. No code is needed. I saw Real Technique brushes were discounted at drugstore.com and Walgreen's had Wet n Wild lipsticks at 50% off (my fave drugstore lipstick).
