Check the right side box for “Used” @ $19.99 for 4.
I bought two boxes and have set up half with no issues. One looked like it was opened and repacked. Two boxes had corners mashed in and on seemed to be unopened.
As of this writing it said 19 left, but it said that before I bout two more sets, your mileage may vary, batteries not included.
I dont work for Amazon, I actually despise them, but hey, a deals a deal . . .
Compared to the $169.99 regular price . . . (still scratching my head how they went to $42 a bulb compared to the last time I bought over the past summer I thing at $10/bulb.)
