Thanks for this feedback.  I'll see what the developer thinks and keep you posted.  We will probably make it possible to choose the number of listings returned and then give directions on the site about styling so each user can style it as they want depending on their sites needs.  That way it is versatile for each user.

We don't track UMD movie prices at this time.  If this gets enough votes we might reconsider this but they have not been popular requests in the past.

I'm contacting a developer now to talk about implementing something like this.

Do you have any thoughts on how you would like this to work?  Capability to limit results by console too, or ability to style the listings, or how many to show at one time, etc.

We have both the Xbox One and PS4 versions of that on our site:
