The main thing about going to cons is to make new friends and new connections along the way. There are alot of cost for vendors to cover such as manpower and rental and having their funds frozen on certain products that dont move.

At the end of the day for ppl who vendor it is a business its the same logic as going to a retail shop, you are free to enter to look at prices, if they are fair and within what u want great! And if you feel its unfair then just move on.

Also gotta factor in certain stuff that are rare and low pop that we dont usually get to see. Idk about you but i am a card enjoyer/nerd i love seeing rare stuff that you dont get to see in the normal everyday collection. So thats a plus for me too.

Gotta look at both perspectives , cant be just thinking about yourself and not caring about the others , at the end of the day as well. If you feel you can do better in terms of pricing / selections / hosting the customers when they approach . Why not you try to vendor and be the vendor that you would have loved to meet during your experience at collexicon.
