Fellow Googlers, check out my internal blog for some Google-specific tips on expensing. Aw, heck, I might as well share with everyone. I'll go ahead and take most of this and make a proper external blog post :-) - Adam Lasnik
I had a few points to add to your post, but couldn't fit it in here, so I added them as a comment to your post ;) - Vinoaj Vijeyakumaar
Super, Vinny... much appreciated! :) - Adam Lasnik
