Walmart offers the Frost King 10x15-Foot All-Purpose Clear Plastic House Wrap 2-Pack for $4.88. Choose in-store pickup to avoid the $5.99 shipping fee. That's tied with our expired mention from yesterday and the lowest price we could find by $22. Among other applications, it can be used as energy-saving insulation or used to cover and protect machinery, equipment, supplies, etc.
These freebies are available to anyone with an internet connection, including both Amazon Prime members and nonmembers.
