AI video coupons: how to check a discount and the final cost
4 min read
An AI video coupon is only worth what the finished video costs after it. Before you use one, check five things: when it ends, which model it covers, whether the price is an annual plan, what happens at renewal, and how much you have to spend to get in. An old offer copied by a comparison site is not today's price.
Duble AI is this site's product and has no public coupon. The other tools' offers below were read on their official pages on October 24, 2026, each with its date. No coupon was tried at a checkout.
Five questions to ask about any discount
| Question | Why it matters |
|---|---|
| When does it end? | Expired promotions keep showing up in blogs and videos |
| Which model and plan? | Many discounts cover one model, or only Pro and above |
| Is it an annual price? | "Per month" on annual billing is charged up front for the year |
| What happens at renewal? | A first-month or first-purchase discount is gone the next month |
| What is the minimum spend? | A discount on an expensive plan can cost more than a small pack at full price |
Real offers from October 2026, and what each one teaches
Higgsfield: per-model discounts, with dates
Higgsfield's changelog publishes each offer with a date and a rule:
- Kling 4.0, Oct 21, 2026. A limited-time launch discount. The changelog does not give the amount: the exact price is on the Generate button.
- Wan 3.0, Oct 13, 2026. A free week for subscribers and 60% off on the API until October 31, 2026. The free week applies only to individual plans from Pro up.
- Referral program, Jul 13, 2026. Invited friends got up to 60% off a plan. The program ended on July 16, 2026, so anyone still promoting it is promoting a closed offer.
- Affiliate program, Aug 24, 2026. People who sign up through an affiliate link get up to 50% off for three hours.
Outside promotions, Higgsfield's blog of Oct 20, 2026 lists Plus at $49 a month, or $39 a month billed annually, with 1,000 credits, and says Starter does not include Seedance 2.5. A coupon on Starter does not get you that model.
PixVerse: crossed-out prices and annual billing
PixVerse's information page, with prices it checked on Oct 15, 2026, shows Ultra at $199 a month with a 20%-off label and $249 crossed out. Standard is $10 monthly or $8 a month billed annually, which is $96 charged at once. Plan credits expire at the next cycle.
Viggle and Vidu: "was" prices and first purchases
Viggle shows Pro at $7.99 a month with "Was $9.99" and annual billing 20% cheaper. Vidu advertises up to 17% or 18% off a first purchase, depending on the plan, and 18% less on annual billing. Both first-purchase discounts end after that purchase.
Hailuo: two official prices
Hailuo lists Standard at $14.99 a month in its subscription terms, updated Jul 14, 2025, and at $9.99 in a blog post of Jul 27, 2026. Neither guarantees today's price. In October 2026 its home page also offers 3,000 credits for downloading the MiniMax Design app.
What about Duble AI?
Duble AI has no public coupon. The open offer is the first purchase: an account that has never paid can get its first video with 10 photos for $6.99, once. After that, regular prices apply:
- One-time packs from $4.99, by card (and Pix in Brazil). Credits never expire, with or without a plan.
- Monthly plans by card, which you can cancel any time, and the credits stay.
- A video costs by the second: 3 credits at Standard and 4 at High (Full HD).
There is no free video and no free video trial. If a video fails, the credits come back at once. The full table is in Duble AI pricing, and the cost of running a profile is in how much an AI influencer costs.
How to work out the final cost of a video
A plan discount does not tell you what a video costs. Do the math:
- Take the total charged (on annual billing, the whole year).
- Divide it by the credits it gives in that period.
- Multiply by the credits your video uses at the length and resolution you need.
- Add the retries you expect.
- Check whether leftover credits expire.
The worked version is in the cheapest AI video: how to compare the real cost.
Frequently asked questions
- Is there a Higgsfield coupon?
- Higgsfield's changelog, read on October 24, 2026, lists dated discounts with rules: a limited-time launch discount on Kling 4.0 from October 21, and 60% off Wan 3.0 on the API until October 31. A referral program that gave friends up to 60% off ended on July 16, 2026.
- Does Duble AI have a discount code?
- There is no public coupon. The offer open to everyone is the first purchase: an account that has never paid can get its first video with 10 photos for $6.99, once. Beyond that, packs start at $4.99 and credits never expire.
- Is the monthly price on an annual plan the same as a monthly plan?
- No. The per-month figure on an annual plan is charged at once for the whole year. PixVerse, for example, shows Standard at $8 a month on annual billing, which is $96 charged up front, against $10 on monthly billing. Always compare the total that leaves your card.
- Why does the price on a comparison site not match checkout?
- Promotions end, plans change and many sites copy old numbers. Hailuo itself shows different prices in its subscription terms from July 2025 and in a blog post from July 2026. Trust the checkout and the official page, with the date you read it.
- Does a discount apply to every model?
- Rarely. Higgsfield's discounts, for example, are per model and per plan: the free week of Wan 3.0 only applies from the Pro plan up, and API generations paid with cashback use standard prices. Read which model, plan and period a discount covers.
