I would wait for 2-3 months before making the purchase so you can use the renters money to pay for the entire shipment and analyze their spending trends and see what items they enjoy the most and best prices that would out compete those places. convenience things like toilet paper, tooth paste, tooth brushes, laundry detergent, soap, bounce could be an option, and then you have snacks, cold drinks, phone chargers, etc.

First--do you supply all of their items like shampoo/conditioner, toothpaste, laundry detergent, etc.?  

He buys things like toilet paper and toothpaste in bulk, one year supply at a time

Did you forget to put the cap back on the toothpaste ? 

Tenants are notorious for pulling out the pop up stopper and dropping toothbrushes, hair, toothpaste caps, etc down the drain.Glacier Bay is basically a lower quality Delta.

Us short people are not at risk here, but I have seen way too many ceiling fans that are at about 6'6" that someone installed without thinking.Construction adhesive does not take the place of nails, for most purposes.Don't wire 3 way light circuits to break the ground, leaving a constant hot to the light .Some cheapskate figured out that toothpaste makes a great filler for nail holes before touchups.

Some of these states will have a hard time putting the toothpaste back in the tube any time soon.

What types of food/items/amenities do you provide - Netflix, Cable, microwave, stove, cups, silverware, toothpaste etc the list can be exhausting.

You had to buy all your own shaving cream, toothpaste, etc. with these chits.

The eviction moratorium is an area where it is going to be hard to put the toothpaste back in the tube, particularly for certain states.
