If you want to add something to an existing order, although we can try and add it to save you on freight, we cannot promise we will catch your existing order in time as we do aim to get all orders out as soon as possible. There is a high chance that the team have already picked and packed your order which would mean we can't add to it.
You're welcome to send an email to sales@gktech.com.au as soon as possible and we will be able to check for you.
