I'm a Home Depot guy. Always have preferred shopping there, plus the big company I work for has ties to them.
But I have to give Lowes some big credit, and suggest anyone who is considering a large purchase look there.
I purchased 5 Coleman storage units for my garage - two 3 drawer units, two jumbo tall units, one tall unit. (They can be seen here.) Had them delivered.
The drawer units went together without too much trouble. When you buy these things, you know what you are getting - self assembly, particle board construction.. these are not high end cabinets. I started to put together the first jumbo unit, and when I got the doors out of the box, one of them was heavily damaged. I freaked out - I had visions of having to take everything back, or waiting two weeks to have another one delivered. Or worse yet, sending all of it back and getting something else, losing all the time I spent putting the units together.
I called the store, prepared for the worst. Within five minutes, they had set up a delivery for the next day (today, a Sunday) to come out and get the damaged unit and bring me a replacement. Buy 10 AM, they've been here and gone.
My garage is still a mess.
