Phone Cards

I have used my fair share of phone cards, dialing the local number, putting in the random pin and then getting to call someone for 100mins, which really turns out to be 20 mins. I hate how most phone cards have all these hidden fees, and random charges if you do not use it all within the same call. If I pay $5 and you tell me I’m going to get 500 minutes then make sure it is 500 minutes and let me talk for that time. If its not going to be 500 minutes I rather that you be honest with me and just tell me its going to be 200 minutes. I think that the average consumer rather get the actual value of the card rather than have large unrealistic values for their phone. Also why is it that the convenience store sells me a $5 phone card for $5 and that in china town the same card (which isn’t fake and works just as well) sells for $3.I still laugh ever time I remember this cop who stopped he’s randomly on a busy Toronto street and got out just to buy this $3 phone card. I actual question if he gets paid to do that, so that people like me would trust the phone card stand and buys the cards. Lastly, does anyone really know how they pick the phone card pins? There must be a way to decode it….let me know what you think.
