Go here to buy a 4'x4' raised garden bed kit from Home Depot for only $9, shipped to your home for free. This item is on backorder and says it will ship when they are available again. Sometimes prices like this are typos, or the item does run out and you don't get your order; you won't get charged until it ships, so you don't have to worry about getting charged for something you don't get. One note: the wood in this kit is pressure-treated, and there are studies that show the chemicals used to treat the wood can leech into nearby dirt. You should decide for yourself if this is safe for your family if you plan to grow vegetables in it. I'm planning to line mine with plastic to be extra safe. Thanks, Dealsea!
