What everyday items are you particular about? For example, I'll go store brand/generic on a lot of things to save money, but there are always those few items I'll spend the extra money on just because.
For me, the ones that come immediately to mind are paper towels and toilet paper. I use lots of paper towels with the kids & for everyday cleaning. To me, nothing compares to Viva. And I'm a girl, so quality (read: 2 ply that doesn't feel like sandpaper) matters to me.
So, what stuff matters to you?
