yea i figured something along those lines. generally by the time that happens i probably have another tube of something else and it's easier to just toss it anyway, or it's already been used up completely. take thermalright coolers for example. not knowing that my 2 IFX chipset coolers came with tubes of chill factor (big ones) i got a tube of tuniq TX2 as well, and about 1/3rd of a tube of AS5 left. I also have a Megahalems on the way, so i will probably have another tube sitting in this box i have full of cooler components im not currently using once that shows up tomorrow
