Wal-Mart, Kmart and Lowe's all have large outdoor planters for between $17 and $50, as of 2015. The 20-inch planters range between $17 and $20, while planters over 20 inches hover around the $50 price range.
Urn planters are a popular outdoor style and provide plenty of room for planting flowers, vegetables or plants. Other outdoor styles include the wooden bucket style, which are often the largest of the styles, used for flowers or container gardening.
Prices for outdoor planters are cheapest after the planting season when demand drops. Customers can save more money by purchasing planters when the stores put the items on clearance or offer closeout pricing online.
