Cell Expert via eBay offers this 3-in-1 Universal Clip Lens Kit in Black/Red for $2.90 with free shipping. That's tied with last week's mention and the lowest total price we could find by $3, outside of other eBay sellers. It includes fisheye, wide angle, and macro interchangeable lenses that can be clipped to most mobile devices, including iPhones and Samsung Galaxy phones.

Note: Allow up to eight weeks for delivery.
