Amazon has put a price on a day, and the price is five percent. Since 29 June, every merchant-fulfilled listing has had to carry a handling time that matches how fast the goods actually leave the building. The stated reason is that “every one day improvement in promised delivery time leads to an average 5% increase in sales.” Handling time was never an operations field. It was a bid, and most sellers never knew they were making one.

The two days went first. Amazon withdrew the two-day default at the end of September 2025, leaving one day or none at the account level and two available only item by item. Sellers were moved without being asked. One setting had been standing in for a thousand different supply chains, and each of them now had to speak for itself.

Clothing is where that bites. A merchant holding stock in a room can ship tomorrow; a merchant whose garments are still being cut cannot. Under one default both published the same window, and the buyer could not tell them apart. We read the retirement in July as Amazon resetting its own standard. The June rule finishes the work: the number is now taken from the warehouse rather than typed into the settings page.

The exemptions are the admission. Custom goods, handmade goods and heavy freight are excluded, which is Amazon granting that some things cannot be hurried. Print-on-demand fell outside that sentence. When the rule went live, EcommerceBytes reported that Amazon was still deciding whether print-on-demand qualified, its moderator able to say only that nothing had changed for it. A shirt printed after purchase is made to order in every language but this one.

The advice trade has filed the whole thing under housekeeping. One agency tells sellers that the padding they kept for years “just became a liability” and to audit the catalogue before Amazon does. The counsel is sound and it stops a step early. An audit does not return the buffer; it tells a merchant what he has been promising all along.

Sellers have found their own remedy, and it isn’t speed. One seller on Amazon’s own forum counsels delaying every shipment to the last day, so that “the Amazon bots don’t change the seller’s handling time.” Another paraphrases the rule in blunter terms: “ship EVERY SINGLE ORDER at the last minute, or you will be punished.” Amazon disputes the premise; a sustained thirty-day pattern of shipping early resets the clock, not an occasional fast order. A third explains that he promises a week, is often ready in five days, and does not want the business of anyone unwilling to wait. He is describing a trade the ranking has no column for.

A default is something a platform believes on your behalf; a declaration is something it can hold against you.

The rule has run five and a half weeks. Monitoring works on a rolling thirty days, and a flagged listing gets thirty more before Amazon begins managing the SKU on the seller’s behalf. Its preferred remedy is to set the window from recent shipping history and shield the late-shipment rate while it does. That is a fair offer. It also takes the promise out of his hands.

A merchant may still take a week to make the coat. He may no longer decide what the week costs him.
