You are in the market for a new computer. What do you need to make a rational choice about which computer to buy and where to buy it$?$

A store that sells only one to two brands of computers so you cannot be bombarded with options.

A sales person that sells more computers than anyone else at the store so you can trust that you are getting everything you need.

All the relevant information regarding the specs of the computer and relevant information regarding the policies of the store.

You need enough money to pay for it in full so you do not ruin your credit score which prevents you from having good credit.
