GLK supplies laptop computers to large business.

On $1$ July $2024$: GLK entered into a contract with Chilli, under which Chilli was to purchase laptop at $$500/$unit$.$

The contract states that if TrillCo purchases more than $500$ laptops in a year, the price per unit is reduced retrospectively to $$450/$unit$.$ GLK year end is $30$ June.

As at $30$ September $2024,$ Chilli had bought $70$ laptops from GLK$.$

$=>$ GLK therefore estimated that Chilli$$s purchases would not exceed $500$ units in the year to $30$ June $2025$

$=>$ Chilli would therefore not be entitled to the volume discount.

During the quarter ended $31$ December $2024,$ Chilli expanded rapidly as a result of a substantial acquisition, and purchased an additional $250$ laptops from GLK$.$

$=>$ GLK then estimated that Chilli$$s purchases would exceed the threshold for the volume discount in the year to $30$ June $2025.$
