Abstract: Apparatus and associated methods relate to offering a discounted product requested by a buyer, with offer parameters determined as a function of the discounted product request, in response to detecting a predetermined product demand characteristic, and at a location, time, and discount based on the offer. In an illustrative example, offer parameters may include quantity, location, or time. The product request may be, for example, a request for a discounted product quantity at a requested location and time. In some examples, the product demand characteristic may be demand as a function of time. The discounted product may be provided at a time and location based on a discount code generated for the product. Various examples may advantageously increase revenue limited by off-peak hour and end of day demand characteristics, for example, offering products discounted in response to demand inadequate to consume time-valued inventory and/or to better utilize operation capacity, so that the seller may increase profit.
