Used a Groupon to get some video cassettes converted to DVD.  A couple days after dropping off the tapes, I realized that a video had fallen between the seats of my car.  I was too lazy to ask if it could be added to my group of video cassettes.  A few weeks later I got the call to pick up my DVDs.  I asked about the additional cassette, and was told that they would just do it right away at the Groupon price.  Twenty minutes later I had all of my video cassettes DVDs in hand.  Overall, I would say that worked out well.
