I love these phone cards and I love Tracfone. They have great bonus offers when you buy these larger denomination cards, sometimes for double minutes, sometimes for extra bonus minutes. It averages about 23 cents per minute.The older Amazon reviews from 2002 and 2001 are outdated here. You only use 1 unit per minute if you are calling inside your home calling area (which are normally pretty big). If you are outside your area, you use two units per call. Long distance is free anywhere because you use units based on what area you are in, not who you call.They never had a promotion for 50 free minutes when one bought phones. They only had a free 30 minutes promotion, so the user who had the hassle with Tracfone over 50 minutes didn't read their box or info correctly. They created their own customer service hassle. I've never had a problem with Tracfone or their CS dept, because I read my materials.It's a great deal. If you go to Tracfone's website, they usually have better deals that retailers.
