Second class postage is included with your bride to be mail and Royal Mail aim to deliver this within 2-3 working days... though we know with the changes to how they process second class mail and how it's scheduled to be delivered over a fortnightly timetable, it's usually much, much slower than this.
 
Postage upgrade options for October's mail:
First class letter (delivery aim of 1-2 days)
 
We'll see how this month goes with the upgraded postage and review options moving forward with the potential to permanently upgrade your subscription.
