Conventions in Virginia

Are their any conventions in the state of virginia? I've never been to a convention before and wanted to go to one that was relatively close to where I live to try it out but ive never heard of any conventions in or close to virginia b4.

Here you go, and there happens to be a con this weekend! lol

Thank you. unfortunately im not able to make it to this weekends convention but i am going to try to make it to the next one. How much does merchandise usually cost?
