Best-Buy-Bot. Written in Python


Don’t be a disgrace to society. Don’t use this for any mass buying/reselling purposes.


B3 is a bot thats a newer and updated version of a now deprecated bot called BBB. It’s now improved to be faster, more accurate, and easier to use then before.
B3 automatically purchases an item from BestBuy when it’s available using the given link. Right now it’s just a desktop app but expanding it to more practical
use cases (e.g. running in “the cloud”) may exist in future versions.
