see how many people have seen your listing and send discount offers to people who have the item in their wishlist

Add search options such as searching prices by rarith. Example: Search for reverse holo card prices all at once for multiple sets at once. 

Is there any chance that a list can be made of values of sales of the “Guardians” ccg cards like you have for Pokémon, magic the gathering, and yugioh? I believe they came out in 1995 or 1996

I can never get to it. I type super c nothing I type super contra nothing. There's many more like this and I run into this problem all the time. 

With the skyrocketing popularity of the new CCG, MetaZoo, I would really like to see listings added to pricecharting. This is my primary site to track sets and prices and I believe MetaZoo would be a welcome addition. 

Unfortunately there are way too many "bid sales" posted on ebay, which end up counted as "sold" and totally mess with the real average value of an item....

These people post at low price and have an automatic "bot" which bids over real humans. When bidding time ends, if they did not reach their target sale price, their bot "wins" the sale so it is not a real sale, the price is very low, and it lowers average value of the item on pricecharting...

And the worst thing is that they post again using the same process, and you can see occurences of the same item at low price "sold" 3 or 4 times in a row in only a couple of days.
