Here are some of the sites I have been involved in developing:

BibsBonnetandGowns.com - careful usage of popups to enhance the selection of christening gowns, christening rompers and christening gifts.
Uses audio files to help with pronunciation of the baby names, drop-down menus and a shopping cart etc in the store.

Beautiful Christening Gowns, Unique Baby Gifts, Christening Gifts and Baptism Gifts.
Whispering Pines Catalog -
cabin home decor, rustic furniture and rustic lighting.
Staten Island Resource Guide - MyStatenIsland.com uses an image map with remote rollovers to highlight the three main areas of the island.
Uses a simple, relatively inexpensive e-commerce solution for Totestools Portable Footrests with online purchasing capabilities. Also uses a slide show to best demonstrate the product.
