Dan Pink teaches us that people value experiences over things, and specifically over money.

Send that person a $250 gift cert to share with their spouse/sig-other at one of the top restaurants in their town. For example.

If it is stuff, something creative. Shirts, smirts. We do that too but it's just another shirt.

We send things like a care-package with local Austin foods, a nice pint glass (with our logo, but tasteful) and things like that. Something memorable.
