・customers who purchase over 3,000 yen will receive a small gift

在英文中，表達「購買滿3,000日圓的顧客可獲贈精美禮品」可以用customers who purchase over 3,000 yen will receive a small gift /present 。

We are running a campaign to commemorate the opening of the store, so customers who purchase over 3,000 yen will receive a small gift.
（為了紀念店鋪開業，我們正在進行一項活動，我們將向消費超過 3,000 日元的顧客贈送一份免費禮物。）
