hey girl! i saw your textbook post. as a college senior, i feel your pain...i've spent probably over $1,000 on books throughout college.
one thing you can try is renting textbooks, especially if it's for a class that you don't really care about or know you won't ever look at the textbook after the class. i usually use chegg (dot) com or textbooks (dot) com to rent textbooks. It's a fraction of a cost!
I considered renting books many times, but I have the worst luck ever. I usually just use half(dot)com. I actually posted the pictures of the three books I need on facebook & one person has the most expensive one & is willing to let me borrow it. I figured I’m just going to buy one of the other ones & not buy my communications book, I’ve had this professor before & she posts her lectures online anyways
