14fire via eBay offers the Military Assault Combined Backpack and Rucksack in CP Camouflage for $12.97 with free shipping. That's tied with last week's mention as the best deal we've seen. (It's also the lowest total price we could find now by $3.) It features 600D high-density waterproof Oxford fabric, MOLLE loops, and can be used as a shoulder bag, waist pouch, or handbag.
Of note, five other colors are available for $13.40. Allow up to three weeks for delivery.
