Do disney cruise ships sell disney merchandise?

The only source provided is a Wikipedia article about Adventureland, a themed land at various Disney parks. This article describes the design and thematic elements of the land and does not mention Disney cruise ships or any merchandise policies aboard them. Because the evidence does not address the question about retail offerings on Disney cruise vessels, I cannot confirm or deny that Disney cruise ships sell Disney merchandise. In the absence of relevant data, the safe conclusion is that the question remains unanswered based on the provided information.
