Amazon offers its Prime members the Camillus First Aid 3-Day Survival Kit in Black, model no. 90430, for $25.79 with free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise, it costs an extra $8.59. Alternatively, Walmart has it for the same price via pickup.) That's the best price we could find by $16. It includes food and water for one person, a flashlight with batteries, poncho, survival blanket, hand warmers, light stick, whistle, bandages, antiseptic wipes, first aid creams, ointments, and pain relief medications.
