Is there any cost to join FundraisingFish.com? There is no cost to join FundraisingFish.com. The only obligation for a Cause is that the yearly earning for your Cause must exceed $100/year. This cumulative from all Supporters (but does not include Network Supporters). The reason we require minimum earning is because we want to make sure that everyone is participating in FundraisingFish.com. When everyone participates, everyone succeeds. Quite frankly, $100 is actually relatively easy to obtain with a minimal number of Supporters. If a Cause does not reach the annual $100 minimum profit target, the Cause will be removed from their Network of Causes. The Cause will still receive rebates from qualified purchases by their Supporters.
