[TCML] Re: For Sale: Big radioluminescent lamps!

[Grenadier <teravolt.org@xxxxxxxxx>]

Everyone who ordered a tube will have theirs shipped out today. Sorry for
all the delay, I've been sick with the flu all week. Starting to feel
better now, though.

If anyone else wants to buy one, just let me know! Not the flu; a tube. ;-)
