What are some items that can go into a stress-relief gift basket?

Around this time every year I am tasked with putting together a gift for some of our employees. In the past I've done variations of movie-themed gift baskets with several different candies, popcorn, and a gift card to either Cinemark or Blockbuster. I am typically given around $35 - $40 to spend on each basket. Instead of doing the same thing again this year, a few coworkers and I came up with a "stress-relief" themed basket. So far we have a Starbucks gift card (price depending on my budget), coffee mug, chocolate, a stress ball, one of those little back massagers, and maybe some hot chocolate and marshmallows. The items have to be appropriate for a wide range of people. I have men and women aged 17-50. Any ideas would be much appreciated!

For stress relief I would put in Chamomile tea or peppermint tea over caffeine charged coffee and chocolate. Aromatherapy candles or lotion. Bath and Body works has small ones in "Sleep" for $3. A small heating pad you can put in the microwave. I don't think Starbucks, hot chocolate and marshmallows say stress relief
