Straight Re-buy Situation:

The straight re-buy situation refers to a routine and low-involvement purchase. It has a minimum information need without great consideration of alternatives. Here the buyer has had experience with the seller and there is no incentive to search. It is a repeat purchase.

The buying decisions are made in the purchasing department. There is a predetermined list of acceptable suppliers. If some suppliers are not in this predetermined list they will find it difficult to sell their products to the buyer.
