Promo Codes vs Coupons vs Lightning Deals: The Differences
Promo Codes (Promotions)
A Promo Code is a discount code that you distribute to customers. The customer enters the code at checkout and receives the discount. Promo Codes are not visible in search results -- you must actively distribute them through social media, email lists, or influencers.
Two types:
- Single-use codes: Each code works once. Ideal for targeted campaigns with limited reach, such as product testers or influencer partnerships.
- Group claim codes: A single code that any number of customers can use. Ideal for broad campaigns, such as "SUMMER10" for 10% off.
Cost to you: No additional fees from Amazon. You bear only the discount itself.
Coupons
A Coupon is a visible discount displayed directly in Amazon search results and on the product page. The customer sees an orange badge showing the discount amount and activates the coupon with a single click. No code entry is needed.
Cost to you: Amazon charges EUR 0.60 per redeemed coupon on top of the discount amount. With 100 redemptions at EUR 2 discount each, you pay EUR 200 in discounts plus EUR 60 in Amazon fees = EUR 260 total.
Advantage: Coupons are visible in search results and significantly increase click-through rate (CTR). The orange badge catches attention and immediately signals a price advantage.
Lightning Deals
A Lightning Deal is a time-limited promotion that appears on Amazon's Deals page. Duration is typically 4 to 12 hours, and Amazon sets the window. Lightning Deals have the highest visibility of all three options but are also the most expensive.
Cost to you: Amazon charges a per-deal fee that varies by time period and category -- typically EUR 75 to 150 for regular deals and EUR 500+ during Prime Day or the holiday season. The discount itself is on top of that.

Creating a Promo Code: Step by Step
Step 1: Create a promotion
Open Seller Central and navigate to Advertising > Promotions > Create a promotion. Select the promotion type: Percentage Off or Money Off.
Step 2: Set the discount
Choose whether to offer a percentage discount (e.g., 10%) or a fixed amount (e.g., EUR 3). Set a minimum purchase requirement if desired (e.g., "10% off when buying 2 or more").
Step 3: Select products
Choose the products the Promo Code applies to. You can select individual ASINs or entire product groups.
Step 4: Choose code type
Select between single-use codes and group claim codes. For single-use, Amazon generates a list of individual codes you can download and distribute. For group codes, you define your own code text (e.g., "SUMMER10").
Step 5: Set dates and conditions
Set start and end dates. You can optionally set a budget cap or a maximum number of redemptions.
Step 6: Activate
Review the summary and activate. Promo Codes are typically active within 4 hours.

Creating a Coupon: Step by Step
Step 1: Create a coupon
Navigate to Advertising > Coupons > Create a coupon. Select the products the coupon applies to.
Step 2: Set the discount
Choose percentage or fixed amount. Amazon recommends at least 5% -- data shows that coupons below 5% generate very few clicks.
Step 3: Set a budget
Define a total budget for the coupon. Once the budget is reached, the coupon deactivates. The budget includes the discount amount plus the EUR 0.60 fee per redemption. Example: with EUR 2 discount and 100 planned redemptions, you need a budget of at least EUR 260.
Step 4: Choose audience
You can make the coupon available to all customers or Prime members only. Prime-exclusive coupons can serve as a selling point but limit reach.
Step 5: Set the duration
Choose start and end dates. Coupons can run for up to 90 days. Note: Amazon may need up to 48 hours for approval.
Step 6: Submit
Review the summary and submit. After approval, the orange badge appears in search results and on the product page.

When to Use Which Tool
Product launch
For a new product, Promo Codes combined with external traffic work best. Distribute single-use codes to product testers or through social media to generate initial sales and reviews. Coupons are less effective at launch because your listing has little visibility -- the coupon badge does not help if almost nobody sees your product.
Ranking push
If your product already has some reviews and you want to improve organic ranking, Coupons are ideal. The visible badge increases click-through rate in search results, which Amazon interprets as a relevance signal. More clicks lead to more sales, and more sales improve ranking.
Inventory clearance
For excess stock, especially when long-term storage fees are approaching, high-discount Coupons are the fastest solution. A 15 to 20% discount via a coupon clears inventory faster than a pure price reduction because the badge generates additional attention.
Seasonal promotions
For Black Friday, Prime Day, or holiday campaigns, combine group Promo Codes (distributed via email and social media) with Coupons for Amazon-internal visibility. Lightning Deals are particularly worthwhile during these periods because traffic to the Deals page spikes massively.

Promotions and Repricing: Why the Minimum Price Is Critical
This is where many sellers run into trouble. You create a coupon with 15% off, the effective price drops -- and then your repricer pushes the price down further because a competitor has become cheaper. The result: a double discount and negative margins.
The solution: Adjust your repricing minimum price before launching any promotion.
If your regular price is EUR 29.99 and you create a 15% coupon, the customer pays EUR 25.49. Your repricer needs to know that EUR 25.49 is the effective selling price -- not EUR 29.99. Set your minimum price so that you remain profitable even after the coupon discount.
Concrete example:
- Regular price: EUR 29.99
- Coupon: 15% = EUR 4.50 discount
- Effective selling price: EUR 25.49
- Amazon fees (15% referral + FBA): approx. EUR 8.50
- Cost of goods: EUR 9.00
- Margin before coupon: 29.99 - 8.50 - 9.00 = EUR 12.49
- Margin after coupon: 25.49 - 8.50 - 9.00 - 0.60 = EUR 7.39
- Repricing min-price: at least EUR 25.49 (so the repricer does not go lower)

Frequently Asked Questions
Can I use a Promo Code and a Coupon at the same time?
Technically yes -- a customer can apply both an active coupon and a promo code to the same product. This results in a double discount that can destroy your margin. If you run both simultaneously, calculate the worst case (both discounts stacked) and make sure you remain profitable even then.
How high should my coupon discount be?
Amazon recommends at least 5%. In practice, coupons with 10 to 15% show the best results in terms of click-through and redemption rates. Below 5%, many customers either do not notice the coupon or consider the discount too small. Above 20%, you can often achieve better results with a direct price reduction, because you save the EUR 0.60 per-redemption fee.
Does a coupon affect my organic ranking?
Yes, indirectly. The visible coupon badge increases click-through rate in search results. More clicks typically lead to more sales. More sales improve your organic ranking. The effect is real but indirect -- the coupon itself is not a ranking factor, but the increased sales velocity is.
How long should a coupon run?
For ranking pushes, we recommend 7 to 14 days. Long enough to collect meaningful data, short enough to control costs. For inventory clearance, a coupon can run longer (30 to 60 days) as long as the budget is sized accordingly.
