Long-story-short, I highly recommend Sell My Comic Books to anyone -- whether you are looking to sell your old comic books or buy one/some/more.
My story is my father gave me his old comic book collection. I had no idea about anything comic book related, so I began my Google search.
Sellmycomicbooks.com came up and I began looking through Ash & Sean's website. There were several pages and helpful videos that were relatable to my situation. I followed the instructions on their videos and submitted my quick list.
Within a day I had received a response with detailed instructions on what the next step would be.
Ash was very kind, patient, and helpful, despite my lack of comic book knowledge -- I appreciated that; some other people may get frustrated with customers who lack knowledge on the subject, but Ash took his time with all of my questions.
I had no idea what to expect for the appraisal of the comics I had, but it was quick and fair. I ended up selling over 200+ comic books to Sell My Comic Books.
I am pleased with the interactions I had with them -- and you be will too.
