Who says that Facebook games are a waste of time? If you have a Facebook account and dexterous digits, head over to play the Zombie Mulch game. You get points for mowing down zombies. Once you accumulate a certain number of points, you can earn a $5 coupon for any lawn and garden purchase of $5.01 at the Home Depot. Get even more points to earn $10 and $15 coupons. Coupons are sent to your email address. You can score one of each coupon for a total of $30 in free lawn and garden supplies! Now’s a great time to stock up on shovels, leaf bags, and bedding to winterize your plants.

Tip: double your points and halve the amount of time needed to earn coupons by clicking on the “Benefits of Mulch” button when the game starts, then join the Garden Club email list.

Game On: $5, $10 or $15 off Home Depot Lawn and Garden
