The document discusses various price adaptation strategies used by companies, including geographical pricing, price discounts and allowances, promotional pricing, and differentiated pricing. Geographical pricing accounts for demand and costs in different locations. Price discounts and allowances incentivize early payment, volume purchases, and off-season buying. Promotional pricing uses tactics like loss leaders, special event prices, and rebates. Differentiated pricing discriminates based on demand levels, volume, usage tiers, customer segments, products, channels, locations, and time. Companies adopt pricing structures reflecting these geographic, market segment, and purchasing factors.
