How to Fix Error 18155: Selling Price Below Minimum Threshold
In February 2026 Amazon introduced error 18155, which blocks any price change that falls below a SKU's defined minimum price floor. The error can be triggered by a simple typo (e.g., 100.6 vs 10.06) and prevents the new price from displaying until corrected via the Pricing & Shipping page or the Listing & Price spreadsheet template.
Overview
On February 2026 Amazon sellers may encounter error 18155 when a product’s listed price falls beneath the minimum price floor they have defined in Seller Central. The platform blocks the price change, keeping the listing inactive until the discrepancy is corrected. Resolving the error promptly is crucial to keep listings live and avoid lost sales during promotions or competitive price adjustments.
Key Points
- Price floor breach — The error appears whenever the selling price or sale price you enter is lower than the minimum price you previously set for that SKU.
- Typical typo trigger — A misplaced decimal, such as typing 100.6 instead of 10.06, instantly pushes the price below the allowed threshold and generates the error.
- Two‑step fix — You can either correct the entered price to meet the existing floor or lower the floor itself to accommodate the new price.
- Listing visibility impact — Until the error is cleared, Amazon will not display the updated price, which can prevent purchases if the correct price isn’t shown.
- Bulk‑update option — Sellers with large inventories can adjust minimum price thresholds for many items at once by using the Listing & Price spreadsheet template.
How to Fix Error 18155
- Validate the entered price — Open the affected listing in Seller Central and double‑check every digit. For example, if you intended to list a kitchen gadget at $12.99 but entered $1.299, the system will flag the entry because $1.299 is below the $5.00 minimum you set. Correct the typo to $12.99 and save.
- Adjust the minimum price floor — If the lower price is intentional (e.g., a flash‑sale price of $4.99), navigate to the “Pricing & Shipping” section of the listing, locate the “Minimum Price” field, and enter $4.99 or a slightly lower value that matches your promotional strategy. Save the changes to clear the error.
- Edit via the full‑listing view — For more granular control, select “Edit” → “Full Listing” and switch to the “Offer” tab. Here you can modify both the selling price and the minimum price in a single screen, ensuring they align before submitting.
Analysis & Recommendations
Why This Matters
Error 18155 stops price updates, keeping listings inactive and causing lost sales during promotions. For example, a $8.00 sale price below a $9.50 minimum blocks the promotion until the floor is lowered or the price raised, impacting revenue.
