What are they buying?
Just came across this useful and interesting resource for you e-tailers and e-marketers out there. Right there at the domain we all wish we thought to register in 1996, Shopping.com, they provide a weekly report of the top shopping searches, and the most popular products in various categories. You click down one link to see the top products in over a 100 categories. I can think of a couple ways this can be useful in marketing research, not to mention a keen way to keep tabs on what the rest of humanity thinks is hot this week.
