Pacific Sales is not your run of the mill appliance store. They close at 6pm and they are not open on Sundays. Pacific Sales caters to a specific clientele of people who know what they want.
Their selection of built-in appliances and specialty fixtures (farmhouse sinks etc) are pretty good. If you're looking for Viking, Thermador or Wolf appliances, this is probably the place to be at. They can special order pretty much anything from the brands that they do carry.
Pacific Sales also price matches (except AJ Madison and other online-only retailers) and they offer pretty good discounts on holidays and on some floor models. You have up to 3 months to cancel your order if not yet delivered.
If you have a special kitchen in mind, I'd try to get down to Pacific Sales on a Saturday since that's the only day they keep reasonable hours for the 9-5 employee.
