Home Depot offers the Flood One Coat Protection 1-Gallon Translucent Floor Stain in Natural, Cedar, or Redwood for $17.49. Opt for in-store pickup to dodge the $6.74 shipping charge. That's $17 off list, tied with our mention from last month, and the lowest total price we could find. This waterproof stain features transparent iron oxides that absorb and block the sun's rays.
