Cheap-ass freebies.
Me, I toss 'em into a military issue 30-06 ammo box. When it's full, I seal it into a wooden box, completely surrounded with expanding foam. Then I bury it as a time capsule, the marker reads "not to be opened until <50 years>". No idea why I started this tradition, seemed amusing at the time. I know when I started it, it was right after the last CES show I attended in 1993 ... I wonder what they'll make of all those AOL 3.5 inch floppys layered in with the other junk when they dig it up in 2043, should I not be there to explain (I fully intend to attend!) ...The next box has a selection of AOL CDs, amongst other tat :-)
