Online shopping malls
From Infogalactic: the planetary knowledge core
Online shopping malls are websites that enable a multi-vendor checkout system enabling retailers to sell in one portal and allow the consumer to check out with one single credit card transaction.
Collections of many traders with different offers directly on the same website are also sometimes known as online shopping malls or virtual shopping malls.
Notable online shopping malls include eCRATER, Shopping.com, Shopzilla, PriceGrabber, and Pikaba.com.
