The cost to renew your Yola Bronze domain hosting package after the first, free, year is CAD$18.45. If you renew your .ca domain at the same time, (CAD$13.95), you pay CAD$32.40 for your domain and hosting renewal. This is how the price you are seeing is worked out.
If you are a Yola Silver subscriber, after the discounted first year, the Yola Silver package costs CAD$107.95 to renew. If you renew your .ca domain at the same time, you pay CAD$121.90 for your domain and Yola Silver renewal.
Please note: Your domain renewal does not form part of your annual Yola subscription renewal. Well before your domain and package are due to expire, you will receive notification emails reminding you of this.
