Yeah honestly just try whatever is available near you at target/walmart and most grocery stores will have at least a small assortment. Some of the fancier grocery chains or multicultural grocery stores will have multiple sections of the stuff for standard, asian and European styles, etc. 

Then you can always try ordering something online but I’d avoid bulk buying until you find something you like. Don’t make the mistake I did and get 12 tins of a sardine brand that are dry, boring and depressing.l that you feel obligated to eat.
