Difference is the useful part
Choice helps when the alternatives answer different needs. It becomes work when a customer has to decode distinctions that do not matter to the task. Five products with unclear roles can be harder to buy than two with visible differences. The question is not whether variety is good, but what the variety lets a person do.
Editing is a commercial decision
An edited range needs a reason for what it contains and what it excludes. That reason can reflect price, use, access, care or the limits of the format. Editing without understanding the mission can remove the item that makes a trip possible. Adding without a role can make the remaining range less legible.
The shelf is a form of information
Arrangement, labels and comparison explain the range before any product description is read. A customer should be able to recognise a starting point and see where a meaningful alternative sits. Abundance without a visible logic asks the shopper to do the retailer's editing work.
Keep the exception in view
No range can answer every need. A useful offer should make its boundaries understandable and support a clear response when it does not fit. Pretending completeness is worse than admitting a limit. The point of enough choice is a dependable answer to a defined mission, not the smallest possible catalogue.
