I get 95% of all my tools from amazon.com nowadays. The deals they frequently have are sometimes amazing. I've saved hundreds buying from them. If you do plan to get a lot of tools from them over the course of a year I highly recommend Amazon Prime. It's a $79 yearly membership where you get unlimited free 2 day shipping or $3.99 per item one day shipping.
You can normally get free shipping but it's not as quick.
Here's some of the things I've gotten on sale from amazon:
Last year, I got
this for $236 to my door. Just yesterday I got
this for $149 to my door. And
this found it's way into my shop for $204. You just have to watch for the price drops and deals. The way I do it is I have anything I want or may want in my cart, and when I check my cart throughout the day it will let you know what items have went down or up in price. You'll want to check your cart several times daily. Be weary that saving money can get expensive at times though...

One more thing I've gotten recently from amazon at a great price: I got
this for $119. Even now at $159-20% the final price of $127.99 is excellent for a top shelf dado set.
