Welcome to the community!
It's a common misconception that the monthly cost of the phone was reduced. However, that was technically not the case. The device cost shown on the website was calcuated after bill credit. The monthly cost of the phone remained the same but customers were getting a credit on their bill to offset the cost of the phone.
While the monthly installment for the phone would still be the $51.25 (before taxes) per month, there should be a discount of $17.92 which would calculate to the stated $33.33 per month.
Hope this helps 😀
Just to clarify,Will I be paying the full $51.25 each month? Or will I pay $33.33 each month and the device balance will lower $51.25 each month. Kind of pointless buying from fido when the price on Samsung Canada is $500 cheaper
