If your after free cyalumes (Actual cyalume brand ones) keep an eye out for threads on here. Every so often I dispose of thousands of cyalumes when they come within 6 months of their expiry date (Though they are still good to go up to about a year after they expire) but it really is first come, first served.
You have to get what your given but there are a number of folks on here who have had some and no complaints yet. :-)
