7.1 拖放——智能购物决策游戏

Smart Shopping – Ask the right questions about price, quality, reviews, and hype before you spend money.
Compare Sources – Use manufacturer info, retail prices, and customer reviews together to judge real value.
Wants vs. Needs – Apply opportunity cost thinking to decide whether a purchase fits your goals or budget.
Hidden Costs – Spot shipping, taxes, and extra fees so the “cheapest” option is truly the best deal.

Think Before Buying – Pausing to evaluate price, quality, and alternatives prevents regret later.
Research & Reviews – Checking multiple sources and verified reviews exposes fake claims and poor products.
Verify Claims – Trust manuals, specs, and return policies over flashy ads; if it sounds too good, investigate.
Total Cost Counts – Always add hidden costs to see the real price, and choose the option that maximizes long-term value.
