Description:
For everyone asking, I used the inspect element in Firefox, switched over to storage, chose local storage and then https://derpibooru.org after which I scrolled down and changed the variable for the dlc_balance property to something high, reloaded the page, calculated the amount of money everything would cost, bought everything, subtracted 1010 from the total cost and set that as a negative value for the dlc_balance property, reloaded the page and done.
