Wedding Shower Pool

Annette and I were thinking that for Amanda and Karyn's shower we could all pool our resources in order to get them something useful. If we each put in $20, or $10 a girl, we would have about $100 in order to get a nicer gift. What do you think? The shower is Thurs night at Laurie's. The grooms are Clark (Amanda) and Mark (Karyn).
