I'd like to see all available editions of a card when I go to purchase one, so I wrote a script to convert the links to name-based searches on TCG.

From: http://store.tcgplayer.com/product.aspx?id=2860 (Just one edition)
To: http://store.tcgplayer.com/products.aspx?GameName=Magic&Name=Counterspell (All editions)

You need Greasemonkey first, then you can install the script from Userscripts.org. Once they're both installed, there will be a menu option under the Greasemonkey User Script Commands menu to convert the links to searches.

Currently it only works for Magic cards -- I may put a little work into figuring out how to make it select the right game, but if you'd like, Greasemonkey lets you edit scripts and you just need to change "GameName=Magic" to whatever game you play (or delete it.)

Feedback is welcome! Enjoy.
