Besides including products that are in a promotion, include products which are best sellers or even featured. You can even add a list of products which are suitable for your customer. This can be achieved in a number of ways; you can select products manually or automate the selection based on a different criteria (i.e. “customers also purchased…”).
A checklist is a type of job aid used to reduce failure by compensating for potential limits of human memory and attention. It helps to ensure consistency and completeness in carrying out a task. A basic example is the "to do list". A more advanced checklist would be a schedule, which lays out tasks to be done according to time of day or other factors. A primary task in checklist is documentation of the task and auditing against the documentation.
