Abstract: Methods and apparatus are disclosed to audit products in stores. An example method includes receiving, at a collection entity, a first request from a first entity to audit a first product, the first request including a first instruction to determine information about a second product that competes with the first product, receiving, at the collection entity, a second request from a second entity to audit a third product, determining that the second request includes a second instruction to determine information about the second product identified in the first request, in response to the second request, generating a second question about the second product, in response to determining that a first question and the second question match, combining the first question and the second question to generate a combined question, and tagging the combined question with an identification of the first entity and an identification of the second entity.
