Abstract: A tiered offer forecasting process is performed on a system executing code contained on a computer-readable storage medium. The process includes receiving purchase records for a product, each of the purchase records including a basket count identifying a quantity of the product purchased and a unit price identifying a purchase cost for the product. Pricing for a tiered offer is received. The pricing includes a first offer price for the product at a first tier, a second offer price for the product at a second tier, and a tier breakpoint differentiating the first tier from the second tier. Consumer acceptance of each of the first and second offer prices is ascertained. The consumer acceptance is utilized to forecast quantities of sales of the product at each of the first and second offer prices. This forecast of sales is provided to a user for implementation in the tiered offer.
