Hello @lfitz,
Welcome to the community!
I understand how you feel and I believe I know what's happening, If Fido usually offers a device for $40/month and they have a promotion for $20/month when you are going through the process on the final step you will see the device cost is still $40 what happens is the cost of the phone will never change but you will receive a monthly credit on your invoice every month for $20 which brings it back to the promotional pricing.
