Storeshopping2014 via eBay offers the Ultra Bright Mini Desk Lamp in four colors (Blue pictured) for $2.79 plus 99 cents for shipping. That's tied with our mention from a week ago as the lowest total price we've seen. (It's the best deal now by $4.) It features a magnetic base and bendable goose neck.
Note, this item requires 3 AAA batteries that are not included.
