Does anyone know if I can sign up for Netflix DVDs by mail only? I've been using my parents' streaming subscription (which I almost never use anyway), but I do miss having DVDs by mail. However, when I use the US Airways link to sign up for Netflix, it brings me to the signup for a one-month free trial which is only for streaming. DVDs can be added to that for an extra $7.99, but I don't see a way to do DVD only. I'd hate to just do the streaming and pay over $48 for a hit.
