In the event that you do not carry the brand, in order to successfully switch the customer without seeming pushy, there are several steps that you should follow:
1. After finding out what the customer wants, ask why he wants the particular item. Remember, if he mentions a brand or item you don't carry, ask which model and style anyway. Knowing the answer to this question is the key to switching. After the customer answers your question, you must give a supportive response to confirm to the customer that you were listening and that you care. Remember, support builds trust.
