In this study, please imagine that you are shopping on an online marketplace and plan to buy a new notebook. The marketplace uses an AI assistant as the seller. The AI seller can answer consumers’ questions and allows consumers to negotiate prices. Your goal is trying to purchase the notebook at a price that satisfies you.

Please interact with the seller as naturally as you would in a real shopping situation. The negotiation will begin with the AI seller’s listing price. For any offer made by the seller, you can take one of three actions:

• Accept the seller’s offer
• Reject the seller’s offer and make a counteroffer to the seller.
• End the negotiation

The negotiation will proceed until an offer is accepted by either party or you choose to quit. After the negotiation, we will ask you a few questions. Answer to the questions have no bearing on your payoff.

We greatly appreciate your time and effort in participating in this study!
