Walmart is selling Energizer Vision HD LED Headlamp 200 Lumens for $ 6.60.
This is half of the listed price. I think it is a very good price.
100 lumens is selling for more.
Here is the link:
+ Free Store pickup otherwise free shipping with orders of $ 35 or more
You could get $ 5 rebate from energizer as posted in another post
That makes 3 for $ 14.80 that less than $ 5 each
