This option is applied ON TOP of regular Signature on Delivery post cost.
For orders under $320, the regular post will be added at Checkout.
Therefore, just choose an Express Post option for the value of your plant order (not including postage).

For orders over $320 postage will not be added at Checkout because our Shopping Cart does not have the option to keep adding postage costs over $320.  Please select the regular post option from the 'Postage Options' tab and then select the relevant Express Post option as well if you require it.
 
Express Post Option.
This option does NOT guarantee next business day postage from Triffid Park.  Each order is put in line as it is received and filled as soon as we can.  During our busy periods, please allow up to 2 weeks before we can process your order.  
The Express Post Option is for Australia Post's delivery service after we have posted your order.

Express Post Guarantee Temporarily Suspended.
22 September 2021 
Express Post remains our fastest postal service, but our next-business-day guarantee is currently suspended. 
This change is necessary due to: 
COVID-19 health and safety regulations applying to workplaces 
fewer passenger flights (which we usually rely upon to carry many of our parcels) 
ongoing COVID-19 disruptions
