I love how many of you say "tough economy, only could put $5, etc etc etc."
You frequently visit a video games forum to buy non-necessity video games! If you are visiting regularly to buy video games then obviously your doing fine because video games are very low on the priority list in "tough times".
If you want to donate, that's really great. If not, that's okay too, but you don't need to "justify" the lack of donation or a small amount.
