Yeah I'm not crazy about Charbucks either, and I literally can't choke down Tim's, it's that bad.
I definitely recommend trying a French press if you are interested. It is a lot different than normal drip coffee, but I like that about it. You can even use a paper filter under the steel mesh if you really want to keep any potential grinds out of the coffee. Bodum is sort of the go-to brand for these things, though cheaper ones can be found pretty easily.
Otherwise, I find that even normal coffee out of a drip machine can be pretty tasty if the beans are freshly ground.
God espresso FUCKS me.
100% try some cold brew. You can buy cold brew at basically any coffee shop nowadays.
And if you really feel like going extra look up lower acid coffee brew recipes for manual brewers like a french press or an aeropress. French press' are cheap and real easy once you memorize the recipe. You just put hot water and coffee in it and set a timer. Bam done.
Also want to tell everyone that switching to using a French Press is a gamechanger when it comes to coffee enjoyment. It does require extra tools, but like OP wrote, they saved $42 in one week, so the cost to acquire these should offset in a week.
Well there you have it. If I got one person to convert, then I did my job. Preach, brothers, preach!
My go to is a Bodum french press and a B & D grinder. If you want to try some great coffee try out Black Rifle coffee(veteran owned and operated).

Here is my coffee setup. My inverter is so large because I also use an induction cooktop. You could get a 1kw inverter. I got pure sine wave. Not sure if it is needed for coffee equipment, it is for the cooktop.

JBC, Rusty Dog, and Ledger are my favorites, with True and Just tied for third .
The grinder is $$, but you won’t regret it.
