Please help anyone.  I' m in phx on vacation and am looking for honest providers that  
accept visa or amex for donations.

You really want to pay in cash much better in the long run.
  Just go to the bank any bank and put the amount on the card and walk out with the cash.
Credit cards leave a paper trail also too much personal information is given out that you don't want out.

See website.  

I do accept debit cards .
