Screen Resolution IS important!

I have also found that there are differences between widescreen laptop and regular desktop monitors. (Ask me how I know!)

Not only should a person check out their site in multiple browsers, but use different screen resolutions as well. As an extra safety measure, it doesn't hurt to check them out on a different type of monitor to be on the safe side. A site I thought looked great on my laptop looked horrible on a normal desktop with a standard CRT monitor.

It's quite simple.

Design for 750px wide (or thereabouts), and know how your site will look to all users, or use a fluid layout.

I prefer the former.

Don't forget we are talking e-commerce here. People want easy navigation, speed, good images, security and confidence that you'll deliver the goods.

Zencart sites don't have to be works of art. Amazon isn't, or Play.com, or plenty of others.

Nothing annoys punters more than horizontal scrolling, and in my opinion, a site that needs it is a bad site.
