Is my product worth selling? The rules we score

You have one product idea and a small ad budget you would rather not lose. Before you spend a dollar, run the idea past the rules below. They are the same rules a careful seller checks by hand, written out so you can check them too.

The price range rule

The product should sell for $20 to $60. Under $20, fees and ad costs eat the profit on every sale. Over $60, buyers need a trust in the seller that a first-time store has not earned yet.

The margin rule

Your cost should be at least 3x less than the selling price. If the product costs you $8, plan to sell it at $24 or more. That margin is what pays for the ads that did not work on the first try.

The problem or wow rule

The product must solve a clear problem or look impressive in a 15-second video. One of the two, ideally both. If you cannot say in one sentence what problem it solves or why it makes someone stop scrolling, an ad cannot say it either.

The size and weight rule

Small and light ships cheaply and survives the post. A product under 200 g in a padded envelope is a different business from one that needs a box with room to spare. Heavy and bulky items quietly take your margin back out.

The not-in-local-stores rule

If a buyer can pick the product up at a local store, they will. What you sell online has to be something they would wait days for. Check the big local retailers before you commit.

The avoid list

Some products fail before the numbers even matter. No battery electronics, because they arrive broken and come back. No fragile items, no sized clothing, because returns eat the margin. No medical goods and no branded goods, because a beginner cannot sell them lawfully or safely.

What a No-go means

A No-go is a judgment against the rules, not a forecast about your future. It says which rule failed and stops there. Fix the idea, pick another, or price this one differently, then check again.
