Walmart offers the Greenes Fence 48" x 48" Cedar Raised Garden Bed for $26.27. Choose in-store pickup to drop it to $24.61. That's essentially tied with our mention from last month and the lowest price we've seen. (Outside of the seller below, it's the best deal now by $12.) It features a depth of 7" and is made from cedar wood.
A close price, Amazon charges $25.11 with free shipping for Prime members.
