  },
  {
    q: "Is there a minimum order quantity?",
    a: "It depends on the product — many personalized and return-gift items have a minimum order quantity shown on the product page, since personalization is usually done per batch. You can't check out below that quantity.",
  },

    q: "Can I personalize my order?",
    a: (
      <>
        Many products have a personalization field for a name, initials, or a short message right on the product page.

    q: "How is shipping calculated?",
    a: "Shipping is calculated by the weight of your order and shown before you pay — no surprises at the end. Orders above a certain value ship free; the exact threshold is shown on the checkout page.",

    q: "How long does delivery take?",
    a: (
      <>
        Standard items are usually packed and handed to our courier within 2–3 business days, with delivery taking a
        further 4–8 business days within India. Personalized or bulk/corporate orders can take longer depending on
        quantity and design complexity — see our{" "}
