Suppose I have a store, and I want to sell bread. Suppose there are two bread factories I can buy from. Factory A is owned by company A, factory B is owned by factory B. Assuming that the bread from company A and B both have the same quality and brand rating, I could do one of these:
- Sell company A's bread exclusively
- Sell company B's bread exclusively
- Sell a mix of company A's and company B's bread
Will there be any difference in retail sales between the three choices above? If so, what causes the difference?
