Owala Leakproof Coffee Mug $21

Through 6/21 (or while supplies last), score an Owala SmoothSip Slider Mug, regularly $37.50, for $20.99 when you use the coupon code CHEERS2YOU during checkout at Keurig. All other stores are charging $23-$30. The real game-changer here is the patented leakproof slider lid, designed to lock in every drop so you can toss it in your bag without worrying about spills or messes. These triple-layered, insulated mugs can keep drinks hot for up to six hours and cold for up to 24 hours. Shipping is free on orders of $35 or more (or when you add two mugs to your cart). Otherwise it adds $7.99.
