This year - buy far less than you might normally. Chances are they will be leaving campus abruptly mid-year or at a minimum parents won’t be allowed to help move in to the dorm room.
Send them with OTC medical supplies, including a thermometer, Tylenol, etc.
If you are driving, these are the best thing ever. My kid flies but uses these to pack things for summer storage.

If you are flying to their campus, consider Southwest. No change fees and if a student + 2 parents go - you can take 2 bags each for free, which will hold 80% of what they need, and carry-on your own stuff.
