$10 or more can be made as a one time donation.  To donate more than $10, simply hit the plus (+) sign at the check-out and this will double and triple (etc) your donation in $10 increments. 
 
Note: Because CYS host the web pages for both Virtues First, Inc. and Farm School - Zambia, funds enter through this CYS website portal and then are allocated from CYS to its karma yoga branch: Virtues First, Inc. VF is a registered  501c3 not-for-profit (that also holds its account in an entirely different bank than CYS).  Virtues First currently only serves one project: Farm School - Zambia. And although there is a 3% processing fee (.30 cents) for this transaction, the remaining $9.70 USD goes entirely to Farm School - Zambia
