My third statement just posted and I am still alive. I posted details in the Wiki. Basically I load ~$2k every other week (~$4k total per month), almost all with $500 GC’s. I usually bill pay it out within 24-72 hours. I’ve only carried a balance of more than $200 for a few days once. After the first month, which is when the first wave of shut downs hit, I started doing 4-5 small (under $10) swipes per month. I also did a couple of ATM withdrawals at WM. No membership fees paid.
My current goal with this is to keep GB alive as a secondary outlet, but I figure even that is up in the air with GreenDot.
