Just by chance, last night I bumped the $$ on my phone card by $50. I use this card all the time to call the US. After I bumped it up, I calculated what I was paying per minute. It was 3.37 cents/minute. And, if you include the fact that they gave me an additional $4 worth of time as a bonus for buying the $50 worth of time, the price dropped to 3.13 cents/minute.
$55.85 on the card gets me 1657 min, therefore 55.85/1657 = 3.37 cents/minute
or if we take away the free $4 worth
$51.85 actually spent gets me 1657 minutes, therefore 51.85/1657 - 3.13 cents/minute
My phone card is the Good Call card which anyone can walk into any postal shop in New Zealand and buy. So that's 8 cents/minute vs. 3.13 cents/minute. And what do you get for spending the extra 4.87 cents/minute? Well, you get to have the calls listed on your phone bill *and* you get to avoid having to enter that big horrible PIN number in when you make a call.
And Telecom sends this offer out like they are doing the NZ public a big favor/service. Jeez!
