My discount code isn't working — what should I do?

What to do when a Lazarus Labs promo or discount code won't apply at checkout.

Only discount or promo codes issued by Lazarus Labs can be applied in the Lazarus Labs checkout. A competitor's discount code, quote code, or promo code will not work in our checkout.

If another supplier has given you a quote or discount code and you want our team to review it, reply in your current support conversation with the details. Our support bot cannot promise a price match, create a discount, or validate competitor codes; a team member needs to review that kind of request.

The member welcome code — WELCOME10

New members get 10% off their first order with the code WELCOME10, typed into the discount field at checkout. For it to apply, all of these must be true:

  • You're logged in to your Lazarus Labs account

  • It's your first order with us

  • Your cart is $80 or more

  • No other coupon code is applied — WELCOME10 doesn't stack with another coupon code, including the separate Frequently Bought Together offer. It does stack with the automatic quantity discount shown when you buy multiple units of the same product.

The code is also shown on your account page and in the cart. If WELCOME10 won't apply, the most common reasons are not being logged in, a previous order on your account, or a cart under $80.

If your Lazarus Labs code won't apply at checkout, it may be one of a few common issues. Work through these once.

Common reasons

  • The code has expired or been disabled

  • The code excludes sale or already-discounted items

  • The code applies to specific products not in your cart

  • The cart hasn't met the code's minimum spend

  • You've already used the code on a previous order (single-use)

What to try

  • Copy and paste the full code into the discount-code field

  • Codes are not case-sensitive, and checkout removes accidental spaces before or after the code

  • Make sure you're entering it in the discount code field, not the gift card field

Still not working?

If a Lazarus Labs-issued code still fails after one retry, it may need a manual coupon or account check. Repeating the same troubleshooting will not resolve an inactive code.

If you're reading this in the Help Center, email [email protected] with the details below. If you're already in an email or Intercom support conversation, reply in the same thread instead. Once you've supplied the exact code and the error or cart details, our team can check the live coupon record; you do not need to repeat the generic troubleshooting or ask separately for a human.

  • The exact code you're trying to use

  • Whether the code came from Lazarus Labs or another supplier

  • A screenshot of the error, if possible

  • The product(s) in your cart

We'll investigate and reply with what's going on.
