The price on a shelf usually reflects decisions made long before the item arrived. For seasonal and imported goods, the commitment often predates the selling season by many months.
How far ahead the commitment runs
Retailers place orders for a season well in advance because factories need production slots, materials must be secured, and ocean transit takes weeks.
For goods made overseas, the interval between order and shelf commonly spans two or three quarters once design, sampling, production and shipping are included.
That means the quantity, the specification and much of the landed cost are fixed before anyone knows how the season will actually sell.
What gets locked and what stays open
Unit cost from the factory is typically agreed at order. Freight may be booked under a contract rate or left to the spot market, and those behave very differently.
Duty is determined by the classification and the rate in force at import, which is after the order was placed and can differ from what was assumed.
Currency exposure depends on the invoicing currency and whether the buyer hedged, which large retailers usually do and small ones often do not.
Why a forecasting miss costs so much
Because quantity is committed early, a retailer that ordered too much cannot simply stop buying. The stock exists and must be cleared.
Clearing it means markdowns, which is why heavy discounting late in a season reflects an ordering decision from long before rather than current generosity.
Under-ordering has the opposite effect. Reordering mid-season means air freight or a missed window entirely, so scarce items hold their price.
How this affects what shoppers see
The relationship between current conditions and shelf prices is loose and lagged. A change in shipping or duty costs shows up when the goods bought under those conditions arrive.
That lag is why prices sometimes move in directions that seem disconnected from the news, and why the effect of a cost change appears gradually.
Categories with short supply chains and domestic production respond faster, which is one reason food and imported durable goods behave differently.
What it means for timing a purchase
Predictable markdown cycles exist because the ordering calendar is predictable, not because retailers choose arbitrary dates.
Waiting trades price against selection, since the sizes, colors and models remaining late in a season are what did not sell.
Knowing that the discount reflects a committed order rather than a temporary promotion explains why some categories reliably discount and others rarely do.
