Amazon offers Prime members the First Aid Only 299-Piece First Aid Kit for $11.74 with free shipping. That's tied with last month's mention as the lowest price we've seen. (Excluding other Amazon vendors, it's the best deal now by $2, although you'd pay at least $17 in local stores.)

It includes a wide variety of medicine, antiseptics, bandages, and injury treatments and comes in a 7.3" x 9.4" x 2.4" fabric zip pouch.
