Moving on a budget

Hi everyone, I’m having to move due to a crappy situation with my roommate, I got pretty last minute notice that I was gonna have to move and I now have 2 weeks before my move date. I’m on a really tight budget with move-in costs and am needing whatever help I can get. I never realized how expensive boxes can be lol. If anyone has some moving boxes they could spare, I’d really appreciate it! I also have been looking at FB marketplace but haven’t had great luck.
