They’re the questions dealers ask us most. Most dealers price off the gross spread and find out at tax time what fees, prep and shipping took. Cash deals over $10,000 come with a federal filing that’s easy to miss when a buyer pays in pieces. Consignment splits get argued over because nobody wrote down who pays for the service. And the “cheapest” marketplace depends on the price of the watch. For the long version, read gross vs net profit for watch dealers and watch dealer profit margins.
