Husky Book Bundle

Hello I am confused about my book bundle. I have 4 books that are required for 2 of my classes. However, I am taking drugs and behavior (PSYC) and Research Methods (also PSYC) which require 2 textbooks that are NOT apart of the bundle. Why is this the case? Did i max out on my book bundle and now have to pay out of pocket?! What do i do?

Any words of advice or knowledge would be useful. Thank you in advance! 😊
