baby shower at work question

Yuta
My work team (7 people) is throwing me a baby shower!  I want to give them a thank you gift but since it is a group and I'm not sure if everyone is pitching in or not I'm not sure what to give.
One idea I have is I can get a bunch of $5 or $10 gift cards for Starbucks, iTunes, etc. and give them all to the lady leading the planning and she can divvy up among those that pitched in?
What do you all think - good idea?  Any other ideas?
