I'm VERY choosy when it comes to certain things...I won't buy cheap laundry detergent...my fav is Tide...and I won't buy the off-brands for most cleaning products.
But, I will try the off-brands for things like canned or frozen veggies, paper items, and some dry goods...if I like them...I'll keep using them...
I think I got my 'label snobbery' from my Mom...if you want a 'comprehensive list' of things...it'll take too long...heheheheh
