if you have a Container Store in your area, they will have a college night at the end of July where everything you buy is 25 or 30% off. You and/or your student does have to register for it and you do have to bring the pass they mail to you but it is an amazing deal! I think when you go to their website, you can prob search for College night? and fill it out. We bought our footlocker there and our daughter uses it a lot! Very handy, she keeps her camera in there, her wallet, her laptop and other important things or papers, and she does have a lock on it. They will pull it out to use as a makeshift table when needed or an extra place to sit. It slides under her bed with no issue.
Also on the bedding, at her university, not ALL beds were XL twin, so I would def hold off on the sheets at least for that. Comforter no big deal, buy that when you find a great price. We also bought her a 4 inch memory foam mattress to go on top (the mattress looked old) and we got that at Costco, came with cover too. There will be SOOOO many deals during the summer...keep an eye out.
Also at Container Store, we bought a refrigerator cart, best item ever!!! Her fridge sits on top of it and on top of the fridge is her little microwave and within the cart are 3 pull out baskets. She keeps her plates, cups, silverware in one and the other two hold are of her snacks. Everyone kept asking where we got it...Everyone..lol
