Walmart offers the DVG 4-Slat Acacia Interlocking Deck Tile 10-Pack in Teak for $41.59 with free shipping. (Amazon is tied and Target charges a few cents more.) That's tied with last week's mention and is the lowest price we could find by $5. They're pre-treated and feature snap-together installation.

Update: Amazon and Target now offer it for $40.99.
