Store employees don't know anything in advance. We know more.
I won a bet in April because a customer heard me explaining something to my friend and wanted my advice (knowing I wasn't an employee) and I told her to wait because the MacBook Pros were being refreshed the next day. An employee interrupted me to tell the customer that I was wrong and "confirmed" with a supervisor that I was wrong. The customer believed me and I was right.
So, long story... still long... pay no attention to the employees!
