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.

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...
