If you plan to do any gardening this year, you may want to sign up for the Home Depot Garden Club. They send a monthly newsletter with gardening tips and project ideas. Each newsletter also contains an exclusive coupon. This month’s coupon was for $5 off a Lawn & Garden purchase of $50 or more. It doesn’t take much to get to $50 when you’re getting your garden started in the spring. These coupons cannot be shared so you need to sign up if you want to get coupons like this in the future.
