Does anyone know how to trace prices via websites? Meaning set up a function, either through CBR or through another portal to track the listed price on trades?
Case in point go here : http://www.blu-ray.com/movies/Back-t...Blu-ray/28800/
When you HOVER OVER LIST PRICE, you see a graph of prices for my randomly chosen BTTF Trilogy, tracked over the past few years.
How can we do that with our comic book pursuits?
I am not tech savy. I hate how much price changes before and after purchase and was wondering if there was a way, or anyone with the know how, we could track this info so we don't burn our funds?
