Some suggestions:
- Include items of all price range (up to $100)
- List sizes, colors, etc.
- Designate one person to keep track of what's been purchased. (I.E., I'd like a new scarf, but check with Lanh to see if the color will work. Or, I want Seasons 5-7 of "Big Bang Theory"; let Caroline know if you're getting one of them to make sure no one else is getting the same one.)
