What are you doing with your Diamond Giveaway Cards

[Casebusters]

Since they are commons and not cards I would collect, I have been trading the common cards for card #417 from 1967 through this year...
What are some ways you are collecting using your giveaway cards ?

on the rare instances that I visit the site i will trade 1 card for 2 cards any time they are offered.
