If you’re a California resident, one really great way to save at Home Depot is to take advantage of their acceptance of competitor coupons! OSH stores nearly always have coupons you can access after taking a 2-5 minute survey. Currently the coupon value is $10 off $30 purchase and you can begin the short survey here. You can print as many times as you like! Use it at OSH, Home Depot or Lowes!
