The tools build on the vast amount of information Google knows about consumers.
Internet shoppers spent an estimated $222 million online last week, an increase of $21 million over the prior week, according to a study by Goldman Sachs and PC Data Online.
Except for toys and flowers, most of those purchases were not intended as gifts. Satisfaction is high, with more than 90% of 3,108 surveyed households saying the experience met or exceeded their expectations. At the same time, 60% plan to buy their holiday gifts at traditional stores and more than 10% through catalogs.
Top purchase categories for online shoppers last week included music, computer software, books, videos/DVDs, computer hardware, toys and health and beauty items.
