I agree with you blazenstar. I myself got lucky one time when I lived in San Antonio, TX. This seller posted on craigs two to three huge albums with 70% mint stamps and old stamps for $30. He asked me to come to his residence. For some reason, that day I didn't look up the address and didn't ask him to meet me in the public place.
So, I went to this guy's home. He opened the garage and brought 3 huge albums and some supplies. And when I was about to pay up, he said, 'Wait! I have more'. And then he brought a shoe box full of loose used stamps and on the top of the box is a 'PENNY BLACK' album(Exact similar to this
