I am very upset that I bought 10 boxes of LED BLUE C6 Christmas lights and come home and put them up on the house only to find that they are two different colors. 5 boxes are blue and the other 5 boxes are a different color. I can not find a way other than mail a letter to complain about this issue and I also can not find any more in my area stores. I am very disappointed that I now have to use half of what I bought this is sad and makes no sense.
