I think he is on the Super Talk 10 plan just like me. Except he only got 50 Bonus minutes whereas I get 150. If you do the math, it works out right and I haven't heard of Rogers having a $10 plan.
$10 + $6.95 + $0.75 + Tax = $20
The plan is normally only offered in Manitoba, Sask., Alberta (one of the three). Either he lives in one of those provinces or he received it through LnR.
