Nothing But Praise
I cannot fault play.com. I've been a regular customer for several years and have ordered close on 1000 DVDs and I can honestly say that only once have they sent me the wrong title which was rectified within three days of reporting the error. They even sent the new title before receiving the one I had.
More recently, I have bought electronic items and infact, ordered a new HD-DVD player on December 27th and it arrived on my door at 9am the very next day.
Yes, everyone cocks up but I have nothing but praise for them.
