If you're buying a low end home system from a high end corporate
dealer and you want demos or a lot of questions answered, shop on
the weekend. During the week salespeople tend to be busy with much
larger sales and aren't very interested in selling one Performa 575.
On the weekends, however, especially on Sundays, salespeople are
often twiddling their thumbs waiting for any customer at all. On the
other hand if you know exactly what you want and how much you want to
pay for it, shop in the middle of a weekday, preferably the day or
two after the ads come out in the local papers. During busy times
salespeople are much more inclined to give in to your $650 cash offer
for a Quadra 605 just to get you out of their hair.
