YouTube continues to offer a selection of HD movies to stream for free (with ads). That's tied with our mention from a month ago and around $3 to $5 less than you'd pay for a rental of these movies elsewhere. Movies include The Terminator (pictured), Europa Report, All Dogs Go to Heaven, and Zookeeper.
Before you spend another dollar on items and services like these, check with your public library. You will likely be surprised by what it offers for free.
