Yeah, that's a good point. If I had T-Mobile I think I could justify that with multiple lines for my family, but I don't currently have T-Mobile. I don't mind switching and they do have some good offerings, but it seems like other options are best for us. Still interesting though. Good catch with the $10 minimum!
I know I would mess up the pack of gum thing (that's what they're banking on!) but that kind of stuff is a good option and I should be looking for similar easy organic things like that.
