Your order will usually be processed on the same or next business day. Whether it’s same or next business day depends on the time of your order. Generally speaking, orders before 12pm will be processed same day. Orders after 12pm are generally processed the following.

This happens in 95% of cases. Please note that due to matters out of our control, processing may take a little longer in rare cases. If you order on the weekend, your order will be processed on the NEXT business day. Orders are NOT processed and fulfilled by our warehouse on weekend days.

Deliveries in Australia with Australia Post generally take between 3-5 business, depending on your location. Deliveries to Melbourne and Sydney are generally 1-2 business days.

Please keep in mind that once the parcel leaves our warehouse we don’t have any control over when it will arrive. Sometimes it’s super fast and other times it can be delayed.

We work incredibly hard to get your parcel to you quickly, but because we ship with third party carriers once it’s with the courier it is out of our hands.

So we just need to wait. However, we rarely experience any significant delays. If you believe that your parcel is significantly delayed, returned to sender or missing please contact us on Facebook Messenger or send us an email to our dedicated customer service line. So we can provide the fast possible response, please provide your order number and the actual name you ordered with.

All queries will be responded to within 48 hours. However, you will likely receive a response much faster on weekdays. Please note that our customer service is not manned on weekends so you will not receive a response until the next business day.

Whilst we endeavour to provide assistance super fast, we will not tolerate abuse or customers who send three messages within a day regarding the same matter. Anyone who does this with will be placed at the back of the queue.

We want to make sure you receive your Happy Mammoth products ASAP, so make sure you enter the correct shipping address and right contact name of the person who will be able to receive it at the time of purchase. This is your responsibility.

If you make a mistake, or things change, contact us immediately and we may be able to modify your order. We can’t make any promises, as we process and ship our orders as fast as possible, but we’ll do our best for you!

Please note that we get charged $9.00 by our warehouse for providing incorrect addresses because it creates a lot of extra hassle slows down the efficiency of the warehouse. If you provide us with the wrong address, you will incur this $9.00 charge before we make the change.

Our discount codes do not work for subscriptions, so please make sure to select the one-time purchase option. Note that only one discount can be used per order, and once per customer.

One golden rule to keep in mind is to never mix more than 4 products at the same time. However, there are products that simply do not go together - so we’ve put together a HELP DESK  where you have all the instructions you need to create your perfect routine for ideal results.

If you need more guidance, do not hesitate to contact us before you begin. This way, we can work together on setting you up for success.

Deliveries to international destinations outside Australia typically arrive within 2-3 weeks, although it’s possible for them to arrive even sooner.

Please note that once your parcel leaves our warehouse, the exact arrival time is beyond our control.

The delivery speed can vary, as it depends on several factors related to the carrier, such as traffic congestion, adverse weather conditions, incorrect addresses and/or customs processes in your country of residence.

These factors and others not listed can significantly affect the prompt delivery of packages, and unfortunately, these circumstances are not within our purview. We appreciate your patience and cooperation in this matter.

Have a question? Get in touch with our friendly customer service team for assistant. All queries will be responded to within 48 hours. However, you will likely receive a response much faster on weekdays. Please note that our customer service is not manned on weekends so you will not receive a response until the next business day.
