Cool idea.  I'll see what other users think about it before implementing, but I like the concept.

Duplicate.  Closing in favor of:

I think they are different enough that they warrant their own issues, but they are definitely closely related and when one is implement there is a very good chance the other will be too.

There have not been many votes for this feature yet.  We plan to work on something that would give the same outcome you are looking for but some other options too.  Basically you would be able to make your own custom "set" you want to collect.  SNES Licensed games, NES Homebrew, N64 Capcom games, etc.

The value might have decreased after that sale.  I'm not disagreeing with that.  The $290 price was probably too high so the price was "corrected" back to $247.  If you look at the historic CIB prices.  The price has been about $240-260 for about 8 months.  

I think your idea to mark sales as "poor" quality could be helpful for people.  Probably need to do the same for "great" quality though.  I'm not sure how we would automate that determination though.  The photo is really the best way to tell and our photo bots aren't smart enough to differentiate condition.

Can you give me a bit more information about this missing item?  What is the full name?  Or do you have a link to it somewhere online so I can look at a photo?

Our pricing algorithm will take into account outliers.  One really low priced game will not impact the price.  There will always be a range for CIB though because the condition is such a big factor.  This particular game has sales prices from $770 down to $145.  Our valuation is $247 after factoring in all the sales data and when they happened.  The CIB game will be roughly $247 in "normal" condition.  Really good condition will be higher and really bad condition will be lower.  

We want to display all of those sales so users have an idea of the low end and high end too expect for their exact item.  But individual outliers will not change the price much, if at all.

Would this be on browse results by set feature?  Like this one:

Or some other page on the site?  Thank you for clarifying.

You can filter all "for sale" results to just the category you want.  In the "Filter/Sort" section choose "Video Games" category.  That will be your default category on future visits too.

You cannot use the back button when adding comics.  You need to enter the series manually each time.  

Does that work for you?
