Koi Scrubs Promo Codes & Coupons February 2026

Your Koi Scrubs promo code likely shows "invalid" because it's expired, already used on your account, or doesn't apply to sale/clearance items in your cart. Many codes like the 20% off sitewide ones have strict eligibility requirements.

Common scenarios include entering unverified codes that worked recently for others but have timed out due to Koi's frequent code rotations. Koi's checkout validates codes server-side against current promotions, often rejecting those that have been overused (such as free shipping over $49 codes).

1. Clear browser cache/cookies or try incognito mode to reset session data.
2. Verify code on koihappiness.com promotions page for freshness.
3. Remove sale items from your cart; codes rarely stack with ongoing markdowns.
4. Contact Koi support via chat if your order under $49 is blocking shipping codes.

Pro tip: Test codes early in checkout before adding shipping information—Koi auto-applies free shipping over $49, saving your code for additional discounts.

No, Koi Scrubs does not allow stacking multiple promo codes on one order. Their system applies only the highest-value code at checkout.

This is consistent with user experiences where attempts to combine codes (like 20% sitewide with 40% clearance codes) trigger "invalid" errors. Koi's platform prioritizes one discount per transaction, with sitewide codes typically overriding others.

1. Apply the best code first in the promo field during review.
2. If it fails, swap to a higher percentage one like 30% off select items.
3. Use free shipping over $49 as a non-code bonus instead.

Pro tip: Pick the code with the highest savings on your full cart value—run a quick subtotal calculation before checkout for maximum impact.

Koi Scrubs student discount codes typically do not work on sale or clearance items, as they exclude already-discounted products per standard promotional terms.

Users often report "invalid code" errors when trying to use student discounts with clearance items, since Koi reserves student perks for full-price items only, aligning with common practices among scrub brands to prevent over-discounting.

1. Add full-price items to cart.
2. Enter code in promo field—success shows instant deduction.
3. Remove sale items if rejected; retest.

Pro tip: Pair student code with free shipping over $49 on full-price bundles for the biggest savings without clearance conflicts.

If your Koi Scrubs promo code applies initially but vanishes at final payment, it's often due to tax/shipping recalculation or cart changes triggering revalidation.

This issue has been noted particularly when switching between mobile and desktop, or when address updates change fees beyond code thresholds like $49 for free shipping. Koi's system re-checks eligibility after shipping information is entered.

1. Note the code and subtotal where it worked.
2. Back out to cart, re-enter code exactly (case-sensitive).
3. Finalize shipping first, then promo—avoid making edits afterward.
4. Switch browsers if the problem persists.

Pro tip: Screenshot the applied discount before reaching the payment page to dispute with support if it drops—Koi chat support resolves most of these issues quickly.

Yes, Koi Scrubs first-time customer promo codes, like the 5-10% off new buyer deals, are one-time use only per account or email.

These are typically listed as "5% off first orders," with confirmation that they expire after one redemption, preventing reuse. The codes are tied to account cookies/IP addresses.

1. Create new account/email for eligibility.
2. Apply at checkout—discount applies once.
3. Subsequent orders will require standard promotional codes.

Pro tip: Use incognito mode for testing, but use a real new email for legitimate first-purchase savings—combine with $49 free shipping threshold for maximum value.
