This is a good exercise. I thought I was pretty good until I saw your list. True confession time:
2 CC's with $49/year fees (IHG) - Gets us at least 2 "free" hotel nights/year.
1 CC with $69/year fee (SWA) - Usually good for a few free/reduced price tickets. We're not flying anywhere these days.
NYT - $1/week. Used to do WaPo, but like NYT better.
Amazon Prime - DH uses this a lot and I'm not going to get between him and AP. He mostly buys parts to fix things and he's a fan of their scratch-and-dent sections. If I want something, he orders it. I don't need the temptation in my life, lol.
Netflix/Hulu/Disney+ (so we could watch Hamiton) were gifts from Bonus Kid. When he moves out, I'm not sure what we'll do. Of course, this does mean we have cable as well, but no HBO or whatever else they have.
That's all I can think of. I'll have to ask DH. I have to say I was vigilant about this stuff pre-FIRE, but pay less attention these days. Overall, we're always under budget.
Before I break my arm patting myself on the back, I'll reveal that we do own a (paid-for) fancy-pants diesel RV. With fuel prices these days, those small economies pale in comparison. Good thing we believe in the save-where-it-doesn't-matter-and spend-where-it-does theory.
ETA: Oops, forgot about the Costco Membership. Mine was free for many years because my brother works there, but we both got married and I had to get my own. Dh and I have the $120 Executive Membership and just last week I cashed over $600 worth of rebate checks. It all went into my wallet, because the one who remembers to take the checks to Costco gets to keep the cash, right?
Another oops: I took advantage of s Super Bowl deal and bought a Sam's Club membership for $8. I wanted a couple of specific things, and I plan to utilize it for a large event later this year. I doubt I'll renew, but I deliberately didn't put DH on the account. If I use it enough, I'll let my membership lapse and do another promotional membership in his name. My Sam's doesn't have gas, but the one near our rentals does.
