Akeem has an awesome collection of books and Japanese swords doesn’t he? I love visiting him as a vendor! You may notice that the books get more expensive as they go up in value, which of course makes sense considering how much more XP you save by reading them. Right before I released BETA I lowered the price of all of the books by a little bit to make them a bit more affordable, here are the base prices now.
Low Grade Books - $250
Medium Grade Books - $500
High Grade Books - $750
Your Haggle obviously sets the price the player will pay, to a value as high as 200% above cost for those with a level 1 Haggle. So if you have a Haggle 1, you would pay double ($500 for a Low Grade Book). At level 10 Haggle you would pay only the base cost ($250 for a Low Grade Book). So having a high Haggle is obviously better.
