Amazon opened in 1995 selling books it didn't stock itself, fulfilling each customer order by placing a matching order with book wholesalers — but those wholesalers required a minimum order of ten books at a time, a rule built around the assumption that any buyer placing wholesale orders was a bookstore restocking shelves, not a retailer fulfilling single customer purchases one at a time. In Amazon's earliest months it wasn't reliably receiving ten individual customer orders a day, let alone ten orders for the same title, so the minimum threatened to stall order fulfillment entirely.

Jeff Bezos tried the direct route first: asking wholesalers to waive the ten-book minimum for a small fee. They declined. The obvious compliant workaround — buy nine books nobody wants just to hit the minimum — would have been expensive and wasteful at Amazon's thin early margins, so Bezos needed a way to satisfy the wholesaler's order-quantity rule without actually paying for nine unwanted books.

Padded each order with nine copies of a permanently out-of-stock lichen book, satisfying the ten-book minimum on paper while never receiving or being billed for them.

The wholesaler's system only checked order quantity, not whether items were deliverable.

The lichen book was listed but permanently out of stock, so it counted toward the minimum but never shipped or billed.

This let Amazon fulfill single-customer orders without paying for nine unwanted books, preserving thin margins.

The workaround was small-scale and temporary, so it didn't damage the supplier relationship before Amazon gained leverage.

When a rule checks quantity but not deliverability, you can satisfy the letter of the rule with units that will never ship, buying time until you can negotiate a real fix.

The workaround let Amazon fulfill single-book customer orders through wholesalers designed around ten-book minimums without either violating the rule or paying for books it didn't need, buying Amazon runway during its earliest, thinnest-margin months before it later negotiated volume relationships that made the trick unnecessary. Bezos told the story himself in a 1998 talk, three years after founding the company, recalling that he later joked about it directly with the wholesalers involved.
