I'm like you, Jan: some things have to be name brand, but other stuff isn't a big deal. Last weekend we went to
Lidl, a European-based discount grocery store that's making its way to the US. They have a lot of store brand items and they're a great deal. We picked up tortilla chips for $0.39 a bag! I figured that was cheap enough that if we hated them, it wasn't a big deal. They're actually really good and now I wish we'd purchased more. But I refused to buy non-brand-name candy for Halloween, so we didn't get any there. They had Hershey's/etc but the prices for that stuff wasn't low.
But name brand stuff...Yup: it has to be Kraft "blue box" Mac N Cheese! Heck, I know I've talked here before about how my kids won't even eat their dad's homemade MnC. (On the bright side: he still makes it and so it's just more for me!) I have to have good hair care products--they don't have to be expensive but they can't be "discount" or store brand. And coffee: DH and I are becoming more and more snobby about our coffee lol! And I don't buy discount electronics. I wish I could, but whenever I try, I have bad luck. Oh well.
I don't mind some store brand cereals but it has to be Cinnamon Toast Crunch and Lucky Charms. The kids like the store brand Golden Crisp (at least, I think that's what cereal it's supposed to be?) and since I empty cereal boxes into Snapware containers, sometimes they can't tell if it's brand name.
