I think you should improve on your interior design and product arrangement because right now its no different from going into a sundry shop where its all on cabinets with no attractive display or advertisement to entice you to buy. Only the microsoft products are displayed promptly.

You should look and compare with your competitors where its brightly lit and inviting to move around. You should cram things in between like the center aisle, makes it looks almost blocked from the outside.

Only noteworthy thing to say is your LCD and printer department arrangement is nice, the logitech products and speakers not so.
