Walmart offers the Casio Men's Classic Digital Sport Watch in Black for $8.80. Choose in-store pickup to drop the price to $5.87. (With orders of $25 or more, Amazon has it for the same with free shipping.) That's tied with our mention from a week ago and the lowest price we could find by $3. It features a resin case and strap, mineral crystal, quartz movement, digital stopwatch, hourly time signal, calendar, and water resistance to 98 feet.
