Post-Christmas clearance sales are still enticing shoppers, yet stock of this bargain basement booty is dwindling day-by-day. What a great customer service and usability idea to show available sizes from the clearance page so customers don't get excited at a fabulous deal only to discover it's only available in extra-extra-jumbo or super-teenie-weenie. Here's an example from C28.com:
C28 shows sizes in stock for all products, not just sale items, but it's especially useful for the clearance section. It gives customers a better user experience, and customers can scan the entire page of bargains, honing in on the items that are available in their size. C28 also provides drop-down menus where customers can narrow clearance items to just their size.
Fabulous!
