Thanks to reader @beautybybrendanese for this tip!
The Pur Cosmetics 5-Piece Mystery Grab Bag is back HERE and it retails for $15 ("up to a $100 value"). Shipping is $5.95 on orders under $50 (free on orders $50+) but there's a code to get 20% off sitewide right now. Enter SAMPLE20 at checkout and that will bring the grab bag down to $12. Your grand total after code, including shipping, will be $17.95.
If you're new to this grab bag, you can see what the January 2016 grab bag contained HERE. That bag appears to have contained about $92 worth of product, and some of the items were recently discontinued (which is why these grab bags are always so deeply discounted). The contents of these bags always appears to be different each time, so it's a roll of the dice!
Thanks again for the tip, @beautybybrendanese!
