I reckon it's similar like in real-life.

it's like wholesalers, when they purchase order in (huge) bulk/s from the factories, they get more discount. then, main distributors, retailers and smaller retailers (small shops) purchase lesser bulk from the wholesalers, and then sell or resell those to the final customers at higher prices.
