Do fast-food restaurants make their own condiments (ketchup)?
Companies bid to make a certain contract. Say McD’s wants 1 million packets of ketchup supplied to their east coast distribution center in the 3rd quarter of 2008. Whoever can make it to the specification is welcome to bid. Low bid usually wins. Everything they buy is on a contract. Every contract has competing bids. This is the chain store way of doing business. The contractor may or may not be allowed to co-brand.
