I live in Toronto area in canada, but i cant find any prepaid cards in any of the listed stores, such as best buy and future shop. They say they just dont have any in stock. Is it possible that they have stopped stocking the cards?

It could be possible. Its up to the managers to what they sell in their stores. There might not be enough people purchasing them there that they decided it would be better to just not have them in stock.

D: thats not fair at all. Im a loyal customer. But the thing is that they said that they had a stock of 27 25 dolalr cards missing :S
BUT KEEP SENDING IT TO THEM
THIEL STOCK IT ANYWAY
