Problem with mulebuy sheets - need help

I've compiled a list of tips for anyone looking to use mulebuy's sheets feature effectively. After 91+ orders, here's what I've learned: 1. Always check seller ratings before buying. I learned this the hard way with a rings 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 30-7 days to the US in my experience. 5. Compare prices across multiple agents. Sometimes mulebuy is cheaper, sometimes not. Hope this helps someone out there!
