I have some items I’d rather have none then the store brand. Butter, not margarine and I buy a trusted brand. Dove bar soap. The only one I use. Oil of Olay moisturizer. Palmolive green dish soap, the scent brings me back to great memories. But for trash bags, office supplies (except the refills for my Cross pen. I’ve used the same pen since 1978) laundry soap, cane sugar, salt, pepper store brands or non-big name label are fine. Reading the labels is critical for me because of allergies.
