Walmart offers the Stanley 8-Gallon Stainless Steel Wet/Dry Vacuum for $35.63 with free shipping. That's $22 less than our mention from a week ago, an all-time best, and the best price we could find by $8. It features a 6-horsepower motor that produces 100 CFM, dolly with swiveling casters, and 10-foot power cord. It includes a crevice tool, gulper tool, floor tool, and two extension wands.

Update: It's now available for in-store pickup only.
