Guardian Heroes was $15 new back in '98
$30 for Panzer Dragoon Saga
$60 for Radiant Silvergun at Electronics Boutique
most of my US Saturn games were purchased for $20 or less.
Dragon Force is one that never got discounted. I watched the stores for a long time on that one. Eventually it wasn't available except at one Toys r Us, when they were down to the last "claim slip" I finally bought it at full price,which was either $54.99 or $64.99.
Sucks that when I sold it a couple years ago I only got like $40 because ebay's search feature wasn't showing results properly. That's when they started moving to using their prefilled game descriptions, since I didnt use that my auctions didn't show in some search results. Who knows how many sellers got screwed on that. It was near mint with the unused memory card sticker too. I never see those memory card stickers in used copies.
