eCase via Amazon offers the Kmashi Table Lamp for $20.99. Coupon code "4OS4G5ZL" cuts that to $15.99. Plus, Prime members bag free shipping. (Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping costs $6.80.) That's tied with our mention from three weeks ago and the lowest total price we could find by $6. It features three brightness levels and four RGB light modes. Deal ends January 31.
