So, if you know someone else who uses TipJar, you can save postage and service charges and combine your checks and draws.
There is currently no one offering a credit-card to TipJar gateway service, but as soon as someone sets themselves up to do such a thing I will gladly give them a link from this page.
The same goes for using the Automated ClearingHouse banking system. In fact I would like very much to work with a bank in mapping tipjar accounts to bank accounts, much like the online brokerage firms do. But as of October 1997, TipJar is working out of a single bank account.
