Walmart (and various third-party merchants) cut up to 60% off a selection of raised garden beds. Plus, orders of $35 or more qualify for free shipping; otherwise, it starts at $5.99. (Select items may also be available via in-store pickup.) A couple of best bets:

• Greenland Gardener Garden Bed Kit for $21.64 (pictured, low by $4)
• BCP 3-Tier Raised Vegetable Garden Bed for $84.95 ($115 off)
