I recently switched to MCI. They offered me the unbelievable sum of a $250 gift certificate to Amazon.com to switch. I took the bait and ran with it—bought a bunch of CDs just before Christmas. Well, MCI offers really good rates for most things except, oddly enough, to Canada. So instead of paying $0.07 per minute, with MCI I’m paying $0.78 per minute. And I asked them when I switched if I was on all the lowest rate plans, and they said yes. So I spent almost $170 extra on long distance to MCI, before I got the bill and realized and could switch back to AT&T. Now everything’s right with the world again, and my $250 gift certificate only cost me $270.
