I like that the Home Depot Design Center (located near the Metropolitan Target) has an expansive design showcase for renovating and designing your home but also has all (or most of) the offerings of a normal Home Depot.
I enjoy browsing around all the showcases and home decorating items. It definitely has way more accessories and tools for interior decorating than a normal Home Depot. Unfortunately, until I own a house, I'll just continue to browse this area while I'm at the Home Depot to get keys copied or buy a hammer.
