We launched our e-commerce site recently and are looking for opinions and advice on what u think. The site is http://www.worldwidedigitalprinting.com
the login link should be in-line with the rest. I am using FF 3.0 from here and could you simply use table-less approach in designing? That is the way to go as well as in SEO point of view, it is should be that relevant. General though, you have a nice concept.
I like your layout. From a visual perspective, it's nice work . However, the source could use some cleanup, and it fails W3C XHTML validation with 80 errors. I always recommend a little extra work in this department.
