I browse about 12 other U-Haul Self Storage throughout the country. None of them are listed as a shop=doityourself.

They sell some material for packing and storing, but I would not put them in the doityourself category. It would be like putting Fredmeyer in doityourself category because FM also sell similar items as the U-Haul Self Storage.

So I would advocate for removing shop=doityourself.
