+
+### Q: What membership tiers do you have and how do I level up?
+Membership has six levels based on **cumulative historical spending** (excluding VAT and shipping). As soon as you hit a new threshold, your account is **automatically upgraded**. Each tier adds a member-bonus discount:
+
+| Tier | Cumulative spend | Member bonus |
+|---|---|---|
+| Bronze | €1+ | 0% |
+| Silver | €200+ | 1% |
+| Gold | €1,000+ | 2% |
+| Platinum | €4,000+ | 3% |
+| Diamond | €10,000+ | 4% |
+| VIP | €20,000+ | 5% |
+
+(New accounts start as a New Member before reaching Bronze. Some special accounts — e.g. key accounts ("KA") — may have custom arrangements.)
+
+### Q: What volume discounts do you offer (per order total)?
+Volume discounts are based on the **total value of a single order**:
+
+| Order total | Volume discount |
+|---|---|
+| €200+ | 5% |
+| €500+ | 7% |
+| €1,000+ | 10% |
+| €2,000+ | 15% |
+| €3,000+ | 20% |
+| €5,000+ | 22% |
+| €10,000+ | 25% |
+
+### Q: How do the discounts stack?
+The system applies discounts **sequentially**: the **volume discount** (based on order total) is applied first, then your **member bonus** (0–5% by tier) is applied on top, to maximize your savings.
+
+### Q: Do you offer quantity discounts on the same product?
+Yes — in addition to the order-total volume discount, ordering more of the **same product** earns extra:
+- **5–9 pieces**: +3%
+- **10–19 pieces**: +5%
+- **20+ pieces**: +7%
+
+### Q: How do order rewards work?
+To reward loyal customers, the platform returns rewards on each order, which can be **accumulated**. Detailed rules are on the order rewards page on our website.
+
+### Q: Is there a welcome discount for new members?
+Yes — new registrants can receive a welcome discount (advertised as **up to 15% off**) on early orders.
