For now, here's some good advice to hold you over: If you're in need of supplies for your dorm room/apartment, check out your school's classifieds and craigslist - not just to scour the offers, but to post a WANTED ad as well. Also, find your local Freecycle chapter and join it - you'll be amazed at people's generosity. The same is true if you're looking to get rid of stuff! Now is the BEST time to sell it, because everyone is looking to buy new stuff. Post everything you want to sell on your school's classifieds ads (IU's can be found on OneStart, for my fellow Hoosiers), Craigslist, and even Freecycle. (More about Freecycle in an upcoming post - for now, just try to google it and find a local one.)
And for those of you who remember my previous post about selling your textbooks, now is the BEST time to sell them! Read this post for more detailed information. I really recommend listing all of the textbooks you still have at the current price on Amazon. They should sell in the next few weeks.
