oust and febreeze!!!! if your child is not stinky they just may have a stinky roomate. it sounds mean but as stated some kids go off to college and just don't know how to clean on their own. i had a nice but really smelly roomate my frosh year (so bad my mother could smell an odor in the hallway).
as for laundry you must have the right kind of bag. we always had washers/dryers in each building, so a pop up hamper worked. if you have to lug it then you need a bag. also quarters for laundry because you could not get them on my campus, you just had to have them.
bed padding/mattress topper is a must, not a luxury or extra.
i would get what he needs to start, and then the rest will go on clearance at the end of the month. thats when you get things like throw pillows, those folding room chairs, storage furniture, all that fun dorm stuff.
i also had a tool kit and it was handy.
let me give a quick list of what i remember needing:
bedding (sheets, mattress padding/topper, comforter/blanket,pillows)
school supplies
shower stuff (towels, shower sandals, shower caddy w/ showering supplies)
desk lamp/fan/alarm clock/tv/ brita filter
under bed storage/risers may be needed
cleaning supplies (i had an electric broom type thing, windex, paper towels, cleaning wipes, oust & febreeze)
laundry (hamper, detergent, quarters, iron/ironing board, hangers)
tool kit
command hooks and sticky tabs for posters
snacks! (ramen noodles, snack bars, chips, cookies, pb & j etc - fruit i always snagged from the dining hall)
bedding we got at Bed bath & beyond, with coupons and it lasted my brother 2 years and me four. various things like shampoo, soap, towels etc my mother got on sale whereever she could. tool kit would be good to get now with fathers day and sales around the corner. school supplies at
walmart or target before you go, the bookstore prices can be killer!
also encourage them to buy used books or shop around online to nap the best price.
