“Like” Home Depot on Facebook and play their Zombie Mulch game to earn coupons for up to $30 off your Home Depot purchases. I played (this one takes some time) and you can actually earn a $5 off, $10 off, AND a $15 off coupon for a total of $30 in savings! You have to do separate transaction – each for at least $0.01 over the coupon value.
Thanks, Organic Deals!
