We are constantly checking ebay for sales data. Some sales are added minutes after they end, but others take a couple of weeks. Please let me know a particular item that doesn't have recent sales data and I will look into this.
Thank you
You should be able to click the month and year in the upper left corner and then choose the month and year from the list. Much faster than clicking back 60 times.
Here is how it looks in my browser:

Thanks. I'm cleaning that up now. I'm implementing some fixes to match those in the future too.

All sets are included and all cards. We have artwork for all of them and prices for about 70% of cards so far....and more prices and sales data to come.
We plan to add an Android app this year. We are finishing up a few features on the iOS app and then we will be working on the Android app. Hopefully it launches in the near future but we don't have an exact date.
Thanks for those suggestions. I can see how those would be useful.

Thanks. I've added sales for both of those consoles now. Consoles are always trickier for us to add because people use very different names for them and it isn't always clear which listings are for the system vs Halo and an Xbox separately.
