"Love GPA. I'm there at least a couple times a day. So helpful. Wish I had known about it much earlier when I started buying slabs ... GPA is the best service I have ever paid for ... I use GPA whenever selling or buying slabbed books - It's a highly valuable database, and well worth the subscription ... Yep, it's a no-brainer. Why haven't you signed up already?"
