Home Depot is the world's largest home improvement retailer with approximately 500,000 orange-blooded associates and more than 2,300 stores in the U.S., Canada and Mexico. The typical store today averages 105,000 square feet of indoor retail space, interconnected with an e-commerce business that offers more than one million products for the DIY customer, professional contractors, and the industry's largest installation business for the Do-It-For-Me customer.

I am not a strong supporter of Home Depot.  They need to treat their employees better and they often lead to the demise of local hardware and lumber dealers.  That said they to offer items that are hard to get in rural areas.  They do offer in store training.
