Lotta work in that
I dunno if I can avoid them all, but I do what I can.
Some companies I do business with because I am more of a drain on them than a positive. Bank of America. They move my money around, but I don't pay them fees or interest on loads or nuffin. They get a tiny bit from whatever slice of interest they keep on the balance in my account. But it's just checking. A bill paying device. I ditched their credit cards and home loans in the W administration.
A whole lot of this list is stuff I wasn't patronizing anyway. I'm not getting a Pepsi at the KFC these days. So, I adhere to most of this without even trying. Burger King is straight trash. Gateway Computers is STILL AROUND?
But it's harder for me to avoid Comcast, Microsoft, and Paypal.
