How do I use a discount code?

Got a code? Here's how to use it.

At checkout

  1. Add your products to cart
  2. Go to checkout
  3. Find the "Discount code or gift card" field
  4. Enter your code and click Apply
  5. The discount will show up instantly in your order summary

Code not working?

A few things to check:

  • Typos: codes are case-sensitive, double-check spelling
  • Expired: most promo codes have an expiry date
  • Minimum order value: some codes only work above a certain amount
  • One-time use: if you've already used the code, it won't work again
  • Subscription excluded: most discount codes don't combine with our subscription discount

Code still won't apply?

Send us your code plus order details at support@getomniair.com and we'll look into it.
