Take your old Christmas lights to Home Depot from November 5th-15th and get a $3 coupon for each set (up to 5 sets) good on any energy efficient LED Christmas lights. Home Depot LED lights will be $5.97 during that promotion- or only $2.97 each after the trade-in coupon!
Need a good reason to buy? The LED light strings use 80% less energy than tradtional incandescent and string lights. These should save you MORE in electric than the $2.97 you paid for them in one season!
