Mammut coupon questions
Six questions people actually ask us.
Why won't my Mammut promo code work at checkout?
Codes are case-sensitive, so enter them exactly as written and copy-paste them from the email. Check the terms in that email, since a code is valid only during the listed dates and may exclude certain items.
Can I apply a Mammut voucher or promo code after placing my order?
No. Applying a voucher or promotion discount to an order that has already been placed is not possible. Enter the code on the checkout page, in the Payment step, and click Apply.
Does Mammut have a military discount?
Through Mammut Collective, Mammut offers a 30% discount, in partnership with GovX, to active military personnel, veterans and first responders.
Does Mammut offer free shipping?
Ground shipping is free on purchases of $100 or more. Orders below $100 are charged $9.99 for ground shipping, which generally takes 2-5 business days.
Does Mammut pay for return shipping?
Yes, Mammut covers return shipping when you use the prepaid return label included with your order. Returns sent via the US Postal Service, including to PO boxes, APO/DPO/FPO addresses and outside the 50 states, are not free.
How long do I have to return a Mammut purchase?
Full-priced items can be returned within 30 days from the delivery date. Discounted items can be returned within 14 days from the delivery date.
