Groupon offers the Puma Men's Lounge Pants
in Blue (pictured) or Dark Green for $19.99
with free shipping
. That's $6 under the lowest total price we could find for a pair of similar pants elsewhere, although we saw Puma lounge pants in different colors for a buck less in November. They're available in sizes S to XL. Deal ends March 31 at 1 am ET.
