I would choose your KitchenAid mixer more carefully than what is on sale in the coming weeks. Last Thanksgiving I was looking for a KitchenAid mixer, and learned that different stores carry different models. They all look the same, but the motors, and the way the mixers open up to access the mixing bowls, are different. Plus different models have larger bowl capacity, or smaller. I took note of which store carried which model and what price. Then I went to the KitchenAid website and learned about the different models. Most important was the motor watt size. The Artisan series is a 325 watt motor, and a 5 qt bowl, with a tilt head (which I don't love). The one I decided on, the Professional 6 series, has a 575 watt motor, a 6 qt bowl, and bowl lift that I like much better.
Plus, off the shelf, you are limited to the colors in stock. I'm not a fan of the common Candy Apple Red or plain white. Online you may choose from numerous wonderful colors and finishes.
Once I decided on what I was really looking for, I went online looking for best price and best shipping. I chose everythingkitchens.com, and I couldn't have been happier. There was also a manufacturer's rebate at that time that I sent in. This year, you may find a better price at another website. I am just posting my experience from last year. I'm glad I did some research. For a little extra $, I got a much more durable mixer in a wonderful color.
