Sale Price End Date [sale_price_end_date] Field for Product Feeds

Optional for ChatGPT

The sale_price_end_date attribute defines the end date of a promotional or discounted price.

This field allows ChatGPT to understand when a sale stops being valid, ensuring that pricing information remains accurate and trustworthy in AI-powered shopping experiences.

It replaces legacy date-range approaches and works together with sale_price_start_date.

When to use

Use this field when a product has a temporary discounted price with a defined end date.

This field is recommended if:

• You provide a sale_price

• Your promotion is time-bound

• You want ChatGPT to avoid showing expired promotions

• [sale_price_end_date] must be provided in ISO 8601 date format.

Format

• Type: Date
• Format: ISO 8601 (YYYY-MM-DD)
• Repeated field: No
• Schema.org property: Not applicable (AI-only field)

Examples:

Minimum requirements

• Use a valid ISO 8601 date (YYYY-MM-DD).
• Ensure the end date is after sale_price_start_date (if provided).
• Ensure consistency with your actual promotion dates.
• Do not use date ranges or timestamps.
• Do not provide an expired date for active promotions.

SEO / AI Tip

Clear promotion dates help AI systems:

• avoid displaying outdated discounts,
• maintain price accuracy,
• build user trust during checkout.

When sale dates are missing or incorrect, ChatGPT may ignore the promotional price entirely.

For best results, pair this field with:

• [sale_price_start_date]
• [sale_price]
• [price]
