The cheapest thing that qualifies is usually the worst value

Most people arrive at a decision with a number already in their head. It is almost always the lowest number that qualifies — the minimum investment, the entry tier, the cheapest version that still counts.

It is the worst number in the entire range, and the reason is structural rather than anyone’s fault.

What a floor does to a price

Set a rule that says an item must cost at least X to be eligible for something people want, and you have not set a minimum. You have set a magnet.

An item genuinely worth rather less than X cannot be sold at its real value, because at its real value it stops being eligible and the buyer loses the thing they actually came for. So it floats up to X. It has to. And it sits there alongside items that are honestly worth X, indistinguishable to anyone who cannot see the whole market.

Which means the item priced at exactly the floor is, on average, the most overpriced item available. Not because anyone is cheating. Because the rule makes any other price impossible.

The move that follows

Go up ten per cent.

That is the whole insight, and it sounds too simple to be worth the paragraph. But just above the floor, the distortion stops. Nothing is being floated up to meet a threshold, because the threshold is already comfortably cleared. Prices start reflecting what things are actually worth, and the value per unit of money jumps a tier for a difference most buyers would not notice on a mortgage statement.

I have watched people spend an extra ten or fifteen per cent and get substantially more of what they were buying — not marginally more, visibly more — and the only reason they did not find it themselves is that the comparison was invisible to them. The better option sits behind a door they do not have a key to, and the floor-priced one is advertised.

Why you cannot work this out from the outside

Two things have to be true at once for you to see it, and buyers rarely have either.

You have to know the floor is distorting prices, which almost nobody is told, because the people explaining the rules are not the people pricing the items.

And you have to see the comparison set — the thing at a slightly higher price that makes the floor-priced one look like what it is. That comparison usually sits somewhere you have no access to. A portal, a relationship, a list that is not published.

Without both, the floor-priced option looks like the prudent choice. It looks like you are being careful with your money.

The general version

This is not really about any one market.

Any time a rule, a grant, a tax band or a qualification sets a price floor, the same distortion appears underneath it. Minimum spends, minimum investments, minimum order values. The thing priced exactly at the line is the thing that needed the line to justify its price.

I learned this selling objects whose value was genuinely unknowable — where there was no comparable, no index and no honest answer to what is this worth beyond what the person in front of you would pay. In that market you learn quickly that a price is not a fact about an object. It is a fact about a situation.

A floor is a situation. And the item sitting on it is telling you something about itself, if you know to listen.
