Agree the price, condition and included items in writing

Before paying, make sure the conversation clearly records:

• final price;
• any shipping costs;
• stated condition of the item;
• known defects;
• included accessories;
• delivery method;
• any specific terms agreed during the negotiation.

A generic statement such as “deal done” is less useful than a precise recap.

If an important element changes after the agreement, update it in the conversation before paying. A clear transaction starts with shared, verifiable terms.
