If you sign up for Home Depot's garden club HERE, you'll get special coupons and other offers that can save you money. I just received a number of coupons for gardening supplies and a coupon worth $10 off a $50 purchase. Plus, some Home Depot stores take competitor's coupons; mine accepts any Lowe's or Ace Hardware coupons I bring in. Ask your store for its policy regarding competitor coupons.
