COVID-19 Information

As we are based in Sydney, NSW, to remain Covid safe we have reduced the amount of people working both in our office and warehouse. During this lockdown period, we are receiving a higher volume of orders than normal. As such, we may experience a slight delay in processing your order. 

To keep any possible delay to an absolute minimum, we have introduced longer office and warehouse operating hours, along with delivery shifts, to ensure orders continue to be processed as close to 24-48 business hours as possible.

If any delay does occur, we will notify you by email within the standard order processing times.

Please note, Australia Post has temporarily made the 'Next Business Day' guarantee unavailable due to COVID-19 restrictions. Express Post still takes priority and is still being delivered within the 3 business day estimate.

We sincerely appreciate your patience and understanding during this time in assisting us to keep our team safe.
