Grocery
These trends were vastly accelerated in the 18th century, as rising prosperity and social mobility increased the number of people with disposable income for consumption. Important shifts included the marketing of goods for individuals as opposed to items for the household, and the new status of goods as status symbols, related to changes in fashion and desired for aesthetic appeal, as opposed to just their utility. The pottery inventor and entrepreneur, Josiah Wedgewood, pioneered the use of marketing techniques to influence and manipulate the direction of the prevailing tastes.
As the century wore on a tremendous variety of goods and manufactures were steadily made available for the urban middle and upper classes. This growth in consumption led to the rise of 'shopping' - a proliferation of retail shops selling particular goods and the acceptance of shopping as a cultural activity in its own right. Specific streets and districts became devoted to retail, including the Strand and Picadilly in London.
The first display windows in shops were installed in the late 18th century in London. Retailer Francis Place was one of the first to experiment with this new retailing method at his tailoring establishment in Charing Cross, where he fitted the shop-front with large plate glass windows. Although this was condemned by many, he defended his practice in his memoirs, claiming that he sold from the window more goods...than paid journeymen's wages and the expenses of housekeeping.
Price comparison sites can collect data directly from merchants. Retailers who want to list their products on the website then supply their own lists of products and prices, and these are matched against the original database. This is done by a mixture of information extraction, fuzzy logic and human labour.
Comparison sites can also collect data through a data feed file. Merchants provide information electronically in a set format. This data is then imported by the comparison website. Some third party businesses are providing consolidation of data feeds so that comparison sites do not have to import from many different merchants. Affiliate networks such as LinkShare, Commission Junction or TradeDoubler aggregate data feeds from many merchants and provide them to the price comparison sites. This enables price comparison sites to monetize the products contained in the feeds by earning commissions on click through traffic. Other price comparison sites like PriceGrabber have deals with merchants and aggregate feeds using their own technology.
In 2012, a driverless shopping cart was made by Chaotic Moon Labs. The device, called "Project Sk8" or "Smarter Cart" was basically a cart fitted with Windows Kinect (to detect obstacles), and an electric drivetrain, and used in conjunction with a Windows 8 tablet. For smaller stores, shopping baskets with wheels can be used either as a large basket or a small cart. These carts are designed for indoor use only
Past studies determined that retailers who did not offer shopping carts such as Sears suffered lower sales in comparison with retailers who did use shopping carts. Subsequent to the introduction of shopping carts and centralized checkout lines at Sears stores, the company noticed a correlating increase in sales.
