I have a rule that I won't buy meat for more than $5/lb. So I'm at the store today and see sirloin steak for $4.99/lb, which is unusually low. I think, yay, we can grill steaks today.
Of course, you can only get that price if you buy like 3+ pounds, so the total sticker price was around $17. I thought, that's OK, I'll use the best pieces for grilling today, and freeze the rest for stir-fry or what have you.
Then I thought, but $17 is an awful lot and it will make the week's grocery bill higher than I thought it was going to be.
Then I noticed another package of sirloin that was about the right size for two steaks and was $5.99/lb, and I thought, oh I'll get that instead, it's not that much more per pound and I won't have to spend so much.
Believe it or not, I did not second-guess this decision until I was out of the store.
Will someone please facepunch me? Why do our brains play these games with us? Do any of you have any tricks, mantras, etc for negotiating grocery shopping without being a dumbass?
