Dear Sam's Club,
I want you to know this is not easy for me. We've been together for many years, and we've had a lot of good times. But, lately I'm not feeling much love between us.
I am leaving you.
I want you to know, it's not your fault - well, not completely your fault. It's just that things have changed. We've moved apart, and I've found someone else. While she's further away and doesn't have some of the wonderful qualities you do, she makes me happy and really seems to care about me.
Her name is Amazon Prime.
