Harbor Freight is a great place to buy tools. They have a very diverse selection and tons of specialty tools you will not find at Home Depot or Lowes. From floor jacks to welders, power tools to towing accessories and everything in between, you'll find what you're looking for.
The only drawback is most of their products are made in China. While this does provide you with far better prices compared to Snap-On or SK Tools, sometimes the reduced quality isn't worth paying the lower price. I own a lot of HF tools but there are key pieces in my garage that need to be of a higher quality.
Their customer service is great and any issues I've had with their products were resolved quickly with no problems.
