How do I track my order?All Happy Mammoth orders are shipped with full order tracking and require a signature on delivery. There are no exceptions to this.

You’ll be sent an email with your tracking number once your order has been shipped so you can check its whereabouts at ALL times.

How long does ordering processing take?

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.

When should I expect my delivery if I am located in the European Union or the UK? For European Union destinations, delivery typically takes 3–5 business days , depending on your location. For the UK , delivery usually takes 2–3 days. These timeframes will also depend on when we receive the order, as our warehouse works Monday through Friday from 8:30am to 5:00pm (GMT+1). Please note that orders do not ship on the weekends or major holidays.

What happens if my parcel is 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.

Are allergic to the product or an ingredient

All of our products contain a detailed label listing all of its ingredients.
