The type of decision making used when purchasing dress, pants and shirt is routine decision making.
Step-by-step explanation:
Depending upon the involvement shown in buying the products, the type of buying decision making can be categorized as:
• Routine response behavior
• Limited decision making
• Extensive decision making.
Routine response behavior is exposed when the consumer is familiar with the product to-be-purchased and also on purchasing low cost goods. Generally people will show less involvement in frequently buying products.
Extensive Decision Making occurs while purchasing the expensive product. These products are unfamiliar and are not bought frequently. So their involvement level will be high.
