Mianheng via eBay offers the USB Portable LED Light in 10 colors for 77 cents with free shipping. That's tied with our mention from a week ago as the lowest total price we've seen. (Outside of other eBay sellers, it's the best deal now by $2.)
Of note, this item is priced at 99 cents Canadian, and the exchange rate to U.S. dollars may vary at final checkout. Expect two to four weeks for delivery.
