Hello. I'm looking to buy an espresso machine for a gift for a couple. Currently they use a stovetop machine. The guy has a nespresso at work and loves it. Have a couple of questions:
1. We are looking to spend about $200. I've noticed that there are several options for $179. What is the difference between the C90 and the D90.
2. Can you buy the coffee pods at other places than their website? Is there a discount place to purchase these pods in bulk?
