Great feedback! Yes, definitely a reputation system would work and help users. For the shipment problem (the fact that shipping just one comic may not make sense), a solution could be to allow users to specify in their preferences the minimum amount of comics they want to ship. For example, I may choose 5 comics and then the system will match me with another user only when this other users would like to receive 5 of my comics...so that I can ship all these comics to just one user.
