Amazon error 18029: Price is outside the allowed rangeThe submitted price trips Amazon's fair-pricing or error-pricing guards - it is far below or far above the recent price for the ASIN, or outside your configured min/max seller allowed price.How to fix error 18029

Check the price for a misplaced decimal - 9.99 keyed as 999 or 0.99 is the usual cause.

Widen or clear minimum-seller-allowed-price and maximum-seller-allowed-price if your legitimate new price falls outside them.

For a genuinely large price change, move in steps rather than one jump.

If the price is correct and still blocked, use Seller Central's pricing health page to confirm the listing is not flagged as a potential pricing error.
