I have never had a shipment from two different sellers combined. In fact, I've had a single order from one seller split in to multiple orders because e-packet is so much cheaper per ounce than larger packages of similar size. Occasionally I'll place an order that has a guaranteed delivery date in a timeframe I'm okay with, and the seller will extend the purchase protection outside of that timeframe. The other issues I've faced are that sellers will either substitute items for dissimilar items or not ship items at all if they are out of stock. I've never had a seller contest a package not received or package not as described though. I think they just figure they'll make a few dollars here or there on people who have forgotten to contest the order.
