Please recommend best international calling card from UK to USA

Our trip is almost here! Must call home at least once a day for a seven day trip. Have been researching international phone cards- and I'm totally overwhelmed. Is there a brand with reliability, good prices, and low connection fees? My calls won't last more than about five minutes or so at a time. Just to touch base with my family. Thanks everyone!
