I bought and sold comic books on eBay for over 9 years using the user id grandcanyoncomics. During that time I received over 7,500 feedbacks, without a single negative feedback standing.
After all that time, I decided a few months ago I wanted a bit of a fresh start, and also, having been considering for some time I may end up leaving the Grand Canyon state, thereby making that user id outdated, I decided to change my user id on eBay to stockcomics. Stock Comics was the name I bought and sold under when I was a teenager, buying and selling comics via the Comics Buyers Guide.
