🏷️ Decoding Price Tags & "N" Units
Handwritten slips in Beijing contain critical info:
- Seller Code: Shop name or WeChat ID at the top.
- Model & Capacity: e.g., "16PM-256-A" = iPhone 16 Pro Max, 256GB, Grade A.
- Price Ticker: "62" = 6,200 CNY. Prices reset daily at 2:00 PM.
🔄 The Secret of "N" Units (Swap): Look for model numbers starting with "N". These are brand‑new replacement units from Apple service, often with zero battery cycles – highly sought after for export.
💰 Negotiation & Pricing
- Wholesale vs. Retail: Prices on tags are for batches of 5‑10 units. Single unit adds 50‑100 CNY.
- Market Price Fluctuation: Prices reset at 2:00 PM daily. Avoid finalizing too early.
- Warranty: Standard 7‑day warranty (indicated by a small stamp on the bottom screw).
📦 Logistics & Shipping
- Packaging: Vacuum‑sealing and reinforced bubble wrap on ground floor.
- Customs: Dedicated battery lines for Europe/Canada – smooth clearance.
- Insurance: Never skip shipping insurance for high‑value items.
