Query: I'm really confused

On the refill card, it says expire in 30 days. But on T-mobile website, it says "unused minutes are valid for 90 days, except with the $10 card". Which one is correct? Too confusing.Also I don't think long distance cost more than local calls. T_mobile website says that Nationwide long distance is included in the pay-as-you-go service.
