**Option 1 (Concise & Clear):**

> 關於商品折扣优惠和特價的相關資訊。
>

**Option 2 (Slightly More Detailed):**

**Choosing the right option depends on a few factors:**

* **Target Audience:** Who are you writing for? Are they experienced shoppers or just starting out?
* **Website Style:** Does your website use a more conversational or formal tone?
* **Content Focus:** What kind of content will be tagged with “折價”? (e.g., Reviews of discounted products, promotion announcements, etc.)

I recommend using **Option 2** or **Option 3** as they are both informative and enticing. Choose the phrase that best suits your website’s style. Remember to translate the description properly if you’re using a different language version.
