A general card and one per variety
Honey is one thing to whoever buys it, and several to whoever tells them apart. Two levels of card, and clear rules about what always stays separate, like organic and diet.
Someone who types “honey” into their list probably wants honey, any honey. Someone who knows the difference wants eucalyptus or wildflower. With a single card per product, one of those two people always comes up short. So now there are two levels: a general card that gathers everything, and one per variety when the variety matters. Same with dish soap, which can be liquid or paste.
Not for everything. Rice and potatoes aren’t split that way, because there the variety changes what you cook and people already choose it. Each category is decided separately, with a simple question: does it make no difference to the buyer?
I also set rules about what always stays separate, because mixing them up costs trust. Organic only counts if the product declares it. Diet versions — sugar-free, gluten-free, light — never merge with the regular ones. A plant-based cheese isn’t compared with cheese. Frozen ground beef is a different card from fresh. And packs that mix two products have an identity of their own, not that of one of the two.
Behind every rule there are real cases someone reported. Those cases stayed as permanent tests, so a decision made today doesn’t get undone by accident tomorrow.
