A mystery lot attracts because it promises surprise, value, and discovery. But it also raises questions: what can it contain, can we choose the size, are returns possible, is the value guaranteed?
The chatbot must explain the rules without revealing the surprise. It must clarify the limits, exclusions, sizes or preferences taken into account, and return conditions before purchase.
This guide explains how to manage mystery lots with an AI chatbot, to preserve the surprise effect while avoiding preventable disappointments.
Summary
Why do mystery lots demand transparency?
The customer accepts a part of the unknown, but not a total absence of rules. They want to know what is possible, what is excluded, and what minimum value or category is planned.
The chatbot must set a clear framework. The surprise should be about the exact content, not about the primary conditions.
A mystery bundle works when the customer accepts the surprise, not when they discover the rules after payment.

What information should be explained?
The bot must explain the product category, the advertised value, the possible sizes or preferences, the exclusions, any potential duplicates, availability, and return policies.
It must avoid revealing the exact content if the commercial promise relies on surprise.
How to manage sizes and preferences?
If the lot contains clothing, shoes, accessories, or personalized products, the bot must explain whether the size is chosen, estimated, not guaranteed, or limited according to stock.
If preferences are not guaranteed, this must be stated clearly. The customer may accept the uncertainty, but they must be aware of it.
How do we address value?
The value of a mystery lot can be a minimum value, an indicative value, or a comparison with the retail price. The chatbot must use the exact wording of the offer.
It must not promise a precise saving if the composition varies or if prices change according to the products included.
How do you talk about returns?
Mystery lots may have specific return rules. The bot must explain if the complete lot must be returned, if individual items are exchangeable, or if certain sales are final.
This information must be given before purchase, as it strongly influences the acceptance of the surprise.
Which flow to follow?
The flow must preserve the surprise while clarifying the rules.
Identify the mystery lot and the concerned category.
Explain value, sizes, preferences, exclusions, and returns.
Answer without revealing the exact content if the surprise is central.
Verify important constraints before purchase.
Forward ambiguous promises, size errors, or disputes after receipt.
Which messages should be used?
To set expectations: "The exact content remains a surprise, but I can explain the possible categories and the important rules."
For sizing: "Sizing is taken into account based on available options, but some preferences may depend on stock."
For returns: "Return conditions may be different for a mystery box. It is best to check them before purchasing."
When to transfer?
The transfer is necessary if the customer disputes the value, if the received size does not correspond to the announced rule, if the content seems out of category or if a campaign promise was ambiguous.
The bot must transmit the order, lot, announced rule, received content, eventual proof and the customer's request.
Which KPIs should be monitored?
Track pre-purchase questions, returns of mystery lots, value disputes, size errors, content contests, and transfers after receipt.
This data shows if the offer is clear enough to remain fun without becoming frustrating.
Which mistakes should be avoided?
Avoid revealing the coordinates of the surprise, promising an end value, hiding the return policy, or downplaying size constraints.
The chatbot must protect the surprise effect without masking the essential conditions.
How can Qstomy help?
Qstomy can connect the chatbot to the catalog, stock, orders, support rules, campaigns, and customer context to answer clearly, then transfer sensitive cases with an actionable summary.
The chatbot helps the customer move forward without exposing unnecessary data or promising an action that still depends on human or operational validation.
