Subscription order Saturday delivery?

My subscription rolled over today (Friday 14/7) and has been dispatched. I’m confused about delivery as usually it’s next day. Is this still the same with this order or do I have to upgrade (somehow) to the £2 Saturday delivery?

Solution found If anyone faces same issue another time. If your subscription does roll over on a Friday ordinarily delivery will be Monday. However I rang (don’t bother emailing or posting here as you won’t get a reply) and managed to get it delivered for Saturday.
