Would you buy meat from a grocery store that left the bad meat in with the good meat or wasn't clean? Would you buy a car from a sales lot that had totaled automobiles on the front lot? I wouldn't and neither would you. Your website is your grocery store; your car lot. You must have an atmosphere that is pleasing to buyers. One that tells that buyer that you are not an amateur, but instead a trained, seasoned professional. Your site is a direct reflection of your product and that is why that having a well designed website can make or break your sales.
