14fire via eBay offers the Military Assault Combined Backpack and Rucksack in CP Camouflage for $12.98 with free shipping. That's tied with last week's mention as the best deal we've seen. (Outside of other eBay sellers, it's also the lowest total price we could find now by $11.) 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 $13.49. Allow up to three weeks for delivery.
