Which of the following is NOT a common mistake when purchasing a computer?

• A. Overbuying
• B. Underbuying
• C. Locally buying
• D. Skipping warranties

Answer: (D)

Understanding what trips people up when purchasing a computer starts with sizing the purchase to actual needs. It’s common to overbuy, paying for more performance or capacity than you’ll actually use. It’s also common to underbuy, ending up with slow performance or insufficient storage. Buying only from a local store can limit your ability to compare prices, components, and return terms across retailers. Skipping a warranty isn’t automatically a misstep, because most computers include a standard manufacturer warranty, and whether to add coverage depends on cost and your tolerance for risk. So, among typical buying errors, avoiding an extra warranty isn’t generally treated as a common mistake.
