I've had great luck with carpool for starbucks cards at 10% off.
Re: the blue preferred. We got a $150 cash back at the beginning, so for the first 2 yrs it's essentially no fee. Gotta play the rewards right ;)
Your statement makes it seem like you're focusing on average cost instead of marginal cost, which is most definitely NOT playing the rewards right.
The first year you got your $150 bonus and paid your $75 fee. Cool. Now let's suppose it's been 11 months since you applied, and you're contemplating whether you should keep the card and pay the annual fee.
Idk how much you spend at grocery stores. Let's say for the sake of the argument you spend $2k a year. at grocery stores.
If you keep the card, you earn 6% on $2000 = $120. You pay an annual fee of $75, so your total benefit is $45.
If you cancel the card and get the Blue Cash Everyday instead, which earns 3% at grocery stores and has no annual fee, you earn 3% on $2000 = $60.
You're better off by cancelling the card and getting the Blue Cash Everyday instead. The breakeven point if we're just looking at grocery spending is $2500.
But by your logic, your first two years are free so you should stay with the Blue Cash Preferred. That's wrong. You've already earned your $150 signup bonus. That's a sunk gain (as opposed to sunk cost haha). It has no bearing on your decision now.
Incidentally, you could also get the signup bonus on the Blue Cash Everday. And I've ignored the extra cashback you can earn on gas with the BCP, but that doesn't change the point I'm trying to make: claiming your signup bonus makes your first two years free is the wrong way to analyze the situaiton.
