At the bottom of their home page delightfuldeliveries.com displays 3 lists: Top Best Sellers, Top Rated Products and Top Happy Birthday Gifts. Listing top sellers is a well known best practice but delightfuldeliveries.com has created 3, thus making their top seller lists 3 times more relevant.

Top husband to wife gifts
Top wife to husband gifts
Most reordered gifts
Top new favorites for 2007
Top first purchases
