You have NOT been there yet???? If you are close you might as well go by and pick it up but call ahead to get him to hold it for you. He has separate storage location so again better call ahead. Also to make sure he is open as the hours are not typical mall hours. Most of the time he is open till 8 but there is no guarantee. Besides it's always good to meet the owner in person and get to know him
BTW he is not the typical Chinese and does not like negotiating prices, I never do and I have seen others fail. He knows his prices are the best in town and can't be beat shopping across the boarder. But if you do succeed let me know
