Quick answer
Judge a low-margin product by its direct contribution, the cash and space it uses, and any customer need it genuinely serves. If you keep it to support other sales, test that assumption. A product can have a deliberate supporting role, but 'customers expect it' needs evidence and a review date.
Name the reason the product is on the shelf
Choose one item or narrow range that causes debate. Is it there to earn margin, complete a customer's project, attract a visit, demonstrate expertise or provide a convenient local option? Write the main reason in a sentence. 'We have always sold it' is history, not a decision criterion.
An independent aquarium retailer's discussion on Reddit captures this tension: bulky equipment competes poorly on price but may matter to local customers. That is a useful question for many shops, not proof that every low-margin line generates profitable follow-on trade.
Separate the direct result from the assumed benefit
Calculate sales less the relevant product and selling costs on a consistent basis. Note the cash tied up, display space and handling effort. Then list the wider benefit you believe the item brings. Keep that benefit unproven until you have something observable to support it.
For an illustrative example, a shop sells a large item for £80, with £58 product cost and £4 other variable selling costs. Its contribution is £18 before fixed costs. If it occupies a display position for months, compare that use of space with realistic alternatives, not an imagined perfect seller.
Collect evidence without making customers a research project
For a short trial, staff can record whether customers ask specifically for the item, whether suitable alternatives are acceptable and whether a related purchase is part of the same visit. A till basket can show association; it does not prove the larger item caused the other sale.
General pricing guidance recommends considering market needs alongside costs. Apply that principle to your particular customers. A shop serving urgent replacement needs may make a different decision from a destination gift shop, even when the product-level margin looks similar.

Compare more than keep or remove
Possible options include keeping one display model with transparent special-order terms, carrying fewer variants, limiting the line to a season or replacing it with a better-fitting product. Verify supplier terms and actual lead times before promising customers an order-on-demand service.
Be honest about what changes for customers. A sample on display should not imply immediate availability if the product must be ordered. If a particular item fills an accessibility, compatibility or essential-use need, consider that explicitly rather than relying only on a sales ranking.
Make the trade-off visible
Set a review period appropriate to the buying cycle and record what would change your mind. That might be too few requests, frequent lost sales, a supplier minimum that makes the arrangement impractical or better-than-expected direct contribution.
You may decide to keep a modest earner because it supports the shop's offer. That is a defensible choice when the cost is known and affordable. It becomes a problem when every weak product gets the same untested justification and the combined range leaves no cash or space for the core business.
