They fulfill many of the orders from whatever stores have the item you're looking for in stock. That often means they're often pulling from multiple stores to fill one order. If anything, they're costing themselves money by paying for multiple shipments to fulfill an order with free shipping. For me it means that I get my orders delivered quickly, even if they do come in separate packages. I'll take that without complaint. I even get a bonus laugh out of some of the ridiculous packaging, like the one Scott shared with us. I've also had nothing but good experiences with their customer service if/when they're needed.
