- The first decisions are about the type of product or service I am looking for.
- Is it something we need or something we want?
- Can we use another product we already have?
- Can we borrow the product from a relative or friend?
- Is it more convenient to buy it now or to wait to buy it in the future?
- Which are the product specifications that we need the most?
- Can I buy it online or I need to buy it in a "brick and mortar" shop?
- Is this something I can try it in some place and later buy it online?
- Which websites I tend to use? Sometimes, websites, like businesses, change and they become better or worse.
