Thank you to the hundreds of people who answered our price survey. You left fantastic feedback and helped us improve our model.
Here are two changes we made just yesterday to improve it:
1) Stop recording prices for "best offer accepted" listings
There used to be a work around on eBay that let us see the accepted offer price. Sometime recently eBay closed this backdoor solution. You notified us of this change and we fixed it on our end.
Best offers were always a small portion of overall sales volume but they biased the prices higher than the actual price.
2) Use 6 month average of sales on more games
There was lots of agreement on what the price should be and the methods people used to come up with their price.
More than 60% of people averaged the most recent sales.
That is the method we already use for the vast majority of games on the PriceCharting, but some rare games or uncommon conditions (loose, cib, new) used the most recent sale. This will now be a much smaller portion.
Thank you again for your feedback and helping to improve PriceCharting.
