Teresa's Toy Store : Added a Guide on Buying Pokémon Cards

Created a guide on buying Pokémon Cards.

I think that's one thing preventing people from searching on Japanese sites. I used the most common keywords (based on requests) but feel free to message me to ask me to add more. 

Note that I don't guarantee the accuracy of the search results.

Also, if there are no items that come up, it means that all listings for that keywords have been sold.
