I've got +70 days left on my current subscription but have bought a new license in-store because it is currently so much cheaper that the online renewals.

Anyway, as this is a new serial number then what is the easiest way for me to update/renew? If I input my new serial now then I will lose the current remaining days. I assume there is an easier way of doing this.

I have run into this a number of times and find in annoying!  If you purchase a new number as opposed to renewing online you will lose the remaining days of the current subscription even if it is the same product.  I suggest you put a reminder in your calendar a day or two before expiration and then add the new product key.

Hi @marksurgeon71, @David Tursky, welcome to Trend Micro Community and happy holidays!

For your question, if you already purchased a new license or subscription, you need to transfer from current license to the new license. Please activate the new one when the current license expired. Here's a reference doc for the steps on how to change the serial number:

Renewal is a way to add one or two years to your Trend Micro program's license or subscription, and the remaining days or months of current subscription will carry over when purchasing the renewal. 

Also, here are some related online articles for your reference:
