I bought a SIM card from fizz but decided not to change my mobile plan to Fizz. If you're looking to get a fizz SIM card I'll sell you mine for $15! I'm in Montreal or I could mail it to you.
You may have trouble selling it in Montreal, since there are now machines to sell it in the metro. And I don't know if the promotion is still in effect, but, it was only $5 in those machines...
