Infinite Money Glitch [EPUB ebook] 

The most advanced videogame in the world is so popular that the in-game gold is a recognized currency on Earth, but that does not mean it was programmed particularly well. Some of the sentient NPCs have just discovered an exploit in the market and it might just be time to buy their world back from the players. If they can pull it off that is.
Infinite Money Glitch is a hilarious hybrid of a heist and an adventure pulled off by the last group of people anyone would ever expect. After all, who actually remembers the merchant from the tutorial zone? But, he remembers you.
