Just because it's in international waters doesn't mean it has to be in the middle of the ocean. If they're willing to accept being outside the territorial waters of any country but still in the Exclusive Economic Zone of one, then they can sit 24 miles off the coast from a port, and do weekly grocery runs with an ordinary vessel.
If they can't stomach being in somebody's exclusive economic zone (not that it makes much practical difference) then they'd have to be 200 miles offshore, making grocery runs a bit more of a pain but still possible. A reasonably fast ship will get you there and back in a day.
They should pay the government of Nauru to rent their sovereignty. They can keep the "island" above sea level by building a mooring tower and tie seasteads to it. Their territory can be the 200 mile economic zone of Nauru.
Also, there's lots of healthy stuff that can be kept in dry form. (Fruits, Legumes, and grains.) They will also have the ability to keep things frozen. Chest freezers can be highly efficient. Especially if they are not opened very often.
