I've comed across many websites that have really poor design. Sometimes I wonder why they don't do slightly more to at least make it look 'acceptable'? In fact with $60 and purchasing a template from
http://www.templatemonster.com/ would have made a huge difference. You don't want a bad design to drag your sales down. In can turn away 50% or more visitors to leave your site. If you put in so little effort in the design, do you put little effort in customer support, producing products, maintaining quality, site security, providing privacy, etc. Design influences consumer confidence & security. The first impression is in the url, then the design. How many will then reach the product details page, if your design is poor?
