Spend One Dollar

The lady and I are having a small Chanukah gathering and have asked everyone to bring a one dollar ($1) grab bag gift.  Evidently you get points in life if you can stretch a dollar the furthest.

I'm using my Amazon Prime (which you can get for free if you have a .edu address that's not an alumni address) to find a gift that will ship for free that's $1 or less.  So far, the best item I'm not buying is:

It's available on Amazon here for 92 cents. 

I need your help - because if I don't get it, I'm just buying a scratch ticket.  What do you think I should buy that is less than a dollar?
