I don't know about you, but I'm rather fond of Clinique Bonus Time. I love the idea of getting a free makeup bag full of treats with my purchase, and I actually do use and enjoy Clinique's Dramatically Different facial lotion. But don't you hate it when you inevitably get some weird eyeshadow or a lipstick in a color you know you'll never use? Right now, Clinique is offering the Ultimate Choice Gift, wherein YOU get to customize your bag and its contents.
Free bag with $21.50 purchase, and free shipping with promo code FSEMAIL. It might be cutting it too close for a Mother's Day gift, but you could always show her a picture of it and tell her it's on its way... then distract her with mimosas.
