For in-store pickup only, and with stock varying by ZIP code, Walmart offers the Rayovac 10-LED 6-volt Floating Lantern with Battery for $4.92. (Amazon charges the same with orders of $25 or more.) That's tied with our mention from last week and the lowest price we could find by $2. This waterproof lantern floats on water and features a 45-hour run time, 85-lumen output, and 410-foot beam distance.
