And Mxyplyzyk has done a good job. Imitating the feel for their brick and mortar shop on Greenwich, their interface is funky but easy to figure out (though a little slow loading). Not everything is on the site yet, but they're off to a good start. They're worth checking out.
Though you can barely pronounce the darn name, Kevin - the owner of Mxyplyzyk (pron. "Mixee-Plizick") - just called to say that his new website with shopping is up now. Finally. Though we DO live in the 21st century, all the great small homestores are only beginning to pay attention to their websites.
