购买前如何检查 App Store 价格
一份实用清单，帮助你比较不同地区的 App Store 价格，并避免把简单换算价格误认为最终付款成本。
Start with the official price
Use Wolffy as a research helper, but always treat the App Store checkout screen as the final source. Regional price tables can show useful differences, yet taxes, account region, payment method, trials, and subscription terms may change the final amount.
从官方价格开始
可以把 Wolffy 当作研究辅助工具，但最终价格应以 App Store 结算页面为准。跨区价格表能显示有价值的差异，但税费、账号地区、付款方式、试用和订阅条款都可能改变最终金额。
Compare the same product
Make sure you are comparing the same app, same developer, same subscription tier, and same billing period. Some apps have regional versions or different bundles, so a lower price may not represent the exact same product.
确认比较的是同一个产品
比较时要确认应用、开发者、订阅档位和计费周期都一致。有些应用存在地区版本或不同套装，因此更低价格不一定代表完全相同的产品。
Watch subscription terms
A monthly plan can look cheaper than an annual plan during the first month, while annual plans can hide renewal surprises. Check trial length, renewal date, cancellation path, family sharing support, and whether the offer is for new users only.
特别注意订阅条款
月付方案在首月看起来可能更便宜，年付方案也可能隐藏续费惊喜。请检查试用时长、续费日期、取消路径、家庭共享支持，以及优惠是否仅限新用户。
Keep evidence before paying
For expensive apps or long subscriptions, save screenshots of the App Store page, trial terms, and checkout screen. If you later need support or a refund request, exact dates and visible terms are easier to explain.
付款前保留证据
对于高价应用或长期订阅，建议保存 App Store 页面、试用条款和结算页面截图。如果之后需要客服支持或申请退款，准确日期和可见条款更容易说明情况。
