<p>A method and system are provided for using an electronic communication system such as a computer or computer network (e.g., the internet or world wide web, an intranet, LAN or WAN, cellular or mobile telephone, or an audio or visual conferencing system) to perform a transaction between one or more buyers, one of whom acts as a moderator, and at least one seller. A moderator creates a group organized for purchasing a product/service from one or more sellers. A moderator may invite one or more sellers to offer a product/service at a given price, and the moderator may review and potentially forward to the buying group offers to sell from other sellers. When multiple buyers are interested in buying from one or more sellers, opinions of the multiple buyers are considered when the group determines to accept a seller's offer or negotiate with the seller. The moderator may provide seller's offering price and other information to other sellers such that the other sellers submit competing offers.</p> |
