Case Study continued

Diane takes the bus home from the grocery store. On her way home she needs to stop by the school and pick up her children. Today her children are in a school play after school. By the time she gets home, the turkey has spoiled.

Now is the turkey still a good buy using the coupon?

Although the sliced turkey was a great buy, since Diane can't get it in the refrigerator in 2 hours, it will become unsafe and she'll have to throw it away. So, it's no longer a good buy.
