Bridal Shower Gifts - Spa Themed, Need Ideas

I'm going to a bridal shower this weekend, and the bridal party is going with a spa theme. Basically we need to bring her pampering gifts. Does anyone have unique ideas? I know a lot of the girls are already getting her lotions, bathrobes and honeymoon basket related items. Any thoughts?

Thanks!

Maybe a gift certificate to Spa Wish? I got one as a gift for being in my friend's wedding and used it at one of the spas for a massage.

I went to a pampering shower a few years ago and we got a Kiehl's gift certificate (and it was fun getting the samples for myself!)
