Now I have my own personal qualms with Amazon, so I buy from them only as a last resort.
I'm not a huge Amazon fan either, but I felt less "bad" about shopping from them knowing that a small part of my purchase went to support the WW&F. Reading the backlash from other non-profits, I was not alone in that reasoning.
Meanwhile, I made a large Amazon "impulse" purchase this morning... it may be my last hurrah.
