My 2 cents....I am pretty new here and not very experienced in comic buying and selling.,My first transaction was with Glenn was as follows:
I responded to a comic he wanted.that I had.
He made an offer.
I countered.
He met the offer.
He is near my area..I met him,he reviewed comic and paid me agreed upon price in Cash.
After deal was done he spent about an hour giving a novice like me an education on comics in general,also answering my specific questions.
You people be the judge of Glenn's integrity.........he has sold me!
