Wonderfulbuying36588 via eBay offers the 3D Black Dragon 8.6" Temporary Tattoo for 81 cents (C $0.99) with free shipping. Excluding other eBay vendors, that's pennies under our mention from two weeks ago and the lowest price we've seen. (It's the best we could find for such a design today by a buck.) It's waterproof and lasts up to five days.

Note: This item ships from mainland China and may take up to nine weeks to arrive.
