The Home Depot is having their Christmas Light Trade-In Event November 3rd through 13th this year, and you can bring in your used (even broken) incandescent Christmas lights and trade them in for a discount on new energy efficient LED lights. For each string of lights, you’ll receive up to $5 off your purchase of a new LED string of lights, limit of 5 per customer.
Bring in your old, broken or used incandescent holiday light strings to your local The Home Depot store for recycling. Get a discount for each recycled string on a single receipt, in-store purchase of LED lights. Limit 5 discounts per customer.
