I’m a lucky member of the teachers credit union, lucky for many reasons but just one of them is that they offer online statements. Meaning you get no correspondence via traditional mail.
They are also donating $1 into the Teachers Environment Fund for each member who signs up for e-statements.
Ask yourself, do you really need all those paper statements every month? I know I don’t, which is why I’m lucky to have a bank which provides an alternative.
Check if your bank offers the same (or any other institution where you get useless monthly letters) and make the change.
