In 2004 they moved their original West Stadium store into a huge new location, designed by J Bradley Moore & Associates Architects, in the Boulevard Plaza shopping center next to Arbor Farms. Pretty good on the hardware, also has a big kitchen/housewares section as well as a big gardening/outdoor section. Pretty good staff.
Also a second location on Washtenaw Avenue east of Huron Parkway.
