Got a free trial subscription from LOVEFiLM. First round of DVDs arrived the day after I registered.
Depending on your subscription, you get to borrow a certain number of DVDs per month. Probably won't subscribe because I don't like that they count the individual discs in a box set.
Love their envelopes though. You send the DVDs back in the same envelope they arrived in after tearing along a perforation to remove a section and pulling off a protective strip to expose the adhesive. What can I say, I'm easily impressed?!
