The present invention contemplates a computer-implemented, currency-based method and system for the exchange of goods over the internet. The invention provides and maintains an exchange web site and an overall list of items available for exchange. The exchange provides and maintains a medium of exchange, the units of which are termed 'flips', and assigns an exchange value in flips to each item offered for exchange. The exchange also provides and maintains an account for each user. The exchange includes a central computer and a database that maintains a separate library for each user that lists all items offered for exchange by that user, and a separate wish list for each user that lists all items desired for exchange by that user. The central computer analyzes data records input by users to find items that have been offered for exchange by at least one user and are desired for exchange by at least one user. When such an item is found, the central computer selects a first user who offers the item and selects a second user who desires the item to participate in an exchange. The central computer sends contact information regarding the second user to the first user and instructs the first user to send the item to the second user. The central computer deducts the cost, in flips, of the item from the account of the second user, credits the cost, in flips, of the item to the account of the first user, and charges a transaction fee to the second user.
