The deal:
The point is to get drugstore.com to apply the $3 off coupon AFTER deducting the other % off coupons. (The math gurus can explain why).
To get this done, we'll use 2 browsers. One to browse products, and another to purchase the item.
In the first browser:
Open the BOGO 50% off CoverGirl page: http://www.drugstore.com/user/pro...45&trxp2=4
Open the BOGO $3 off CoverGirl page: http://www.drugstore.com/user/pro...15&trxp2=4

Browse selection, and decide which product/color you want (note that it appears in BOTH promo pages. Easily findable as they are sorted by price). Open product page and note if it has 2 coupon boxes, and is ShopRunner eligible.
Leave browser window open, we will copy the address from the product page soon.

In the second browser:
* Click here to activate 15% off: http://e.drugstore.com/a/hBQroRCA...k12dsBF151
* Copy and paste the product page address from the first browser.
* Click ONLY the 50% off coupon. NOT the $3 coupon.
* Add 2 to cart.
* AFTER adding to cart, click on the product in cart (this takes you back to the product page) and NOW click on the $3 coupon, and click Update.
* Checkout.
