Koi CBD Coupon Codes & Discounts (2026): Every Way to Pay Less
Koi runs more stacking discounts than almost any hemp brand — a first-order code, a subscription rate, a service discount, a points programme and rotating seasonal promotions. Used together they take a meaningful bite out of a catalogue that is not cheap at list price.
15% OFF
Your first order — applied at checkout, no code hunting required.
Stack it with free shipping over $69 and the 90-day money-back guarantee.
Current Koi promotions
These are the dated promotions Koi has confirmed through its affiliate programme. We check this table regularly; the standing discounts in the next section are the ones that never expire.
| Code | Offer | Runs | Notes |
|---|---|---|---|
| LABORDAY | Labor Day sitewide BOGO plus a free gift | 31 Aug – 7 Sep 2026 | The biggest Koi promotion of late summer. Code required at checkout. |
| GETMOREKOI | Labor Day tiered promotion — discount scales with basket size | 31 Aug – 7 Sep 2026 | Better than LABORDAY on large orders, worse on small ones. Compare both at checkout. |
| No code | Closeout sale — up to 50% off overstock items | Ends 30 Aug 2026 | Applies to selected products only; discount shows in cart. |
| SELECTBOGO | Flash BOGO on selected products | 17 Sep and 22 Sep 2026 | One-day flash events. Set a reminder. |
| No code | End of Summer sitewide BOGO plus free gift | 22 – 30 Sep 2026 | Automatic at checkout. |
A word on the BOGO offers: buy-one-get-one is only a good deal on something you will actually finish. On a 120-count gummy jar with a long shelf life, it effectively halves an already competitive price per milligram. On a small trial size it just gets you two small trial sizes. Our shelf life guide covers how long these products really keep.
Standing Koi discounts that never expire
First order
Applied to your first purchase. The simplest saving available and it needs no seasonal timing.
Subscribe & Save
20% off every subscription order, plus a free jar of CBD Anytime Gummies worth $13.99 on signup. Cancellable.
Koi Cares
For active and retired military, first responders, medical professionals and people facing financial hardship. Verification required. The single largest standing discount Koi offers.
Good Feels Club
Points on every order redeemable against future purchases, plus early access to sales.
Free shipping
Free economy shipping on orders of $69 or more, typically 5 to 8 business days. Below that threshold you pay for delivery, so it is worth consolidating small orders.
Money-back guarantee
Full refund within 90 days of purchase, and 50% back between 91 and 150 days. Effectively a long free trial.
How to stack Koi discounts properly
The order you apply these in changes what you pay. Here is the sequence that produces the lowest price.
If you qualify for Koi Cares
Get verified first. At 25% it is the largest standing discount, and it applies to all Koi purchases rather than a first order only. Then subscribe on the products you buy repeatedly and let the points accrue.
If you are a first-time buyer
Use the 15% first-order discount on a large jar rather than a small one. The saving is a percentage, so it is worth three times as much on a $129.99 order as on a $39.99 one — and the large jars are already the better value per milligram. It also clears the $69 free-shipping threshold, which a small order will not.
If a BOGO is running
A sitewide BOGO usually beats every percentage discount, because 50% off in effect is larger than 15%, 20% or 25%. Check whether the code stacks with anything else; if it does not, take the BOGO.
If you buy monthly anyway
Subscribe. 20% off every order plus points compounds faster than waiting for seasonal codes, and you can pause it whenever you want.
When Koi discounts hardest
Based on the promotional calendar Koi runs through its affiliate programme, the pattern is consistent year to year:
- Labor Day weekend — sitewide BOGO, the strongest promotion of the late summer
- End of September — end-of-summer sitewide BOGO plus a free gift
- Green Wednesday and Black Friday — the deepest discounts of the year
- 4/20 — reliably heavy promotion across the hemp category
- Closeout and overstock windows — irregular, up to 50% off, worth checking the sale page before a full-price order
If you are not in a hurry, buying on one of those dates rather than a random Tuesday is worth more than any coupon code.
Where the discount is worth spending
A coupon on a bad-value product still leaves you with a bad-value product. These are the Koi items where a discount does the most work, drawn from our full Koi product ranking.
Complete Full Spectrum Gummies 120ct
Already 4.3¢ per milligram at list. With a BOGO it is close to 2¢, which is exceptional.
Full Spectrum CBD Balm 3000mg
3.3¢ per milligram before any discount. The cheapest cannabinoid Koi sells.
THC + CBN + CBD Gummies
The 120-count is the size to buy on a BOGO if sleep is the reason you are here.
Koi Coupon FAQ
What is the best Koi CBD coupon code?
Right now, LABORDAY — a sitewide buy-one-get-one with a free gift, running 31 August to 7 September 2026. On large baskets, compare it against GETMOREKOI, the tiered promotion running the same week. Outside promotional windows, the 25% Koi Cares discount is the largest standing offer for anyone who qualifies.
Does Koi have a first-order discount?
Yes, 15% off your first order. It is applied at checkout rather than requiring you to find a code.
Can I stack Koi coupon codes?
Percentage codes generally do not stack with each other, but the subscription discount, rewards points and the money-back guarantee all apply regardless. When a sitewide BOGO is running it is usually worth more than any single percentage code.
How does Koi Cares work?
It gives 25% off all Koi purchases to active and retired military, first responders, medical professionals and people facing financial hardship, subject to verification. It is the largest standing discount Koi offers.
Is Koi Subscribe & Save worth it?
If you buy the same product monthly, yes — 20% off every order beats the 15% first-order discount after the first purchase, and signup includes a free jar of CBD Anytime Gummies worth $13.99. You can cancel at any time.
Do Koi coupon codes expire?
The seasonal ones do — LABORDAY and GETMOREKOI both end on 7 September 2026. The first-order, subscription, Koi Cares and rewards discounts do not.
Does Koi offer free shipping?
On orders of $69 or more, via economy shipping in about 5 to 8 business days. Orders below $69 pay for delivery, despite the free-shipping banner on Koi’s homepage.
