At one time i went to a site that offered a product for X dollars if I ordered right now. When I logged out and logged back in the price went up. Each time I logged back in the price kept going up until it reached some limit. Is there a WordPress plugin that would do something like that? Could be based on a date after first log in. Each week that goes by, the price increases.
The business purpose is to minimize prospects from shopping the internet for better prices. I know all they would have to do is change browsers, domains, etc. but not everyone knows that.
