The nice thing about the Costco arrangement is that shipping is included in the price. I checked the shipping on those at essupplystore and to Oregon, it is over $12. That's almost as much as the Costco lot WITH shipping. Lots of collectors just want smaller amounts and don't need a 100 lot case.

It is seldom you will find quality new merchandise for less than Costco offers. I'm always amazed at what they come up with, both at the local store and at costco.com
