You might wanna look up meade digital they handle orders like that from what I'm told
It is one of the largest wholesale seafood markets in the world. Many vendors should have sardines but it is primarily a wholesale market with also retail sales. And since it is a wholesale market, the price of fish will be set there based supply & demand for the day. If a company does do online sales, one would have to seek the vendor out individually.
Yes they have sardines and all other fish 🐠. Price are not staying same every day. I am not sure they take order in online.
