what are good options to carry books first year of law school?

i’m an incoming first year and i have no idea how many books were going to have to carry. i’m going to try to get digital versions also but paper is more practical for me anyway. is a tote bag or a firm handbag good with a lot of room? or are backpacks more ideal? let me know what you guys use! my budget is about $100 and idk where to look :
