Seriously. Even the most basic supermarkets stock like at least 10 different kinds of salt. Iodized, non, kosher, sea, for grinding, packets, in disposable shakers, etc., and often a couple brands, e.g. Morton and Diamond. And a larger supermarket will have pink salt (Himalayan), various fancy sea salts, fleur de sel, flavored salts...

The salt options must be customized regionally, because I only get 3 choices.

Found the guy that doesn’t actually shop at the grocery store.
