I've done a special trip or two to Costco just for these, but I didn't just buy a few -- at last count I have about 90 certs in my safe.

But, as much as I love ya guys and gals, I couldn't justify spending my time driving to Costco to get a few certs for someone else and then deliver them somewhere, even though I would earn those 2% + SPG points on it. A Costco card costs $50 (right?), and if I hadn't been a member yet, I would have signed up just for these certs. That said, thumbs up to those who can afford helping out others.
