it all depends what DVD they are, the condition, is it COMPLETE [box, insert, dvd]?..it doesnt matter if you bought it for $20 or not..also it depends on how popular and old the dvd is..the newer the higher the price..the more popular the higher the price..if its anime it MIGHT be higher in price..
-=WARNING=-..some DVD\'s dont have a price so we have a managers choice..in other words WE MAKE THE PRICES on how much we give you and how much we sell it for
