Three quarters of people either regularly or occasionally use the net to research purchases they plan to make in-store, according to data released by BIGresearch reported in DM News. About 80 percent of men said they research electronics online before heading to the store. 71 percent of women did the same for travel services. Income segmentations showed that different groups tended to research different sorts of products. Those with the lowest income most commonly researched food, people with starting professional salaries most researched electronics. Those with $50,000 to $75,000 in income were most interested in housing. The wealthiest proved most interested in financial services.
