Really, whenever you change the channel, buying patterns change - people do not buy the same in malls as in department stores, nor in department stores as in small shops, and so people do not buy exactly the same things online as they do in supermarkets or malls. The channel shapes what is bought. Most shopping online still has an implicit power-law dynamic because of its two-dimensional layout, where being "above-the-fold" or "top of the list" garners the majority of customer attention (and therefore sales).
