Common cnfans coupons mistakes to avoid

I've compiled a list of tips for anyone looking to use cnfans's coupons feature effectively. After 52+ orders, here's what I've learned: 1. Always check seller ratings before buying. I learned this the hard way with a sunglasses order that took forever to arrive. 2. Use the search filters properly - they actually work quite well once you understand them. 3. Don't skip the QC photos. I almost did once and would have received a completely wrong item. 4. Shipping is usually 2-21 days to the US in my experience. 5. Compare prices across multiple agents. Sometimes cnfans is cheaper, sometimes not. Hope this helps someone out there!
