I've noticed that even with groceries WalMart is more $. Now that they have such a large customer base they can do it and people will still shop there. I haven't bought anything from them in a long time as Kroger started carrying Iames cat food.
I was just disapointed thet the niteize was dimmer than the incan bulb, I suppose if you really want long runtime it would work.
I was going to suggest drilling out the end of the tailcap for a lanyard but you said no drilling. But the endcap is pretty much hollow so it would be pretty easy to drill a pair of holes to stick something through and then seal it inside or drill one hole in the center and put in a small bolt.
