No Substitute: Which Products Inspire Brand Loyalty?

When it comes to most things I buy for my home (toilet paper, for example), I am pretty flexible: I will buy what is at Costco or what is on sale, including generic or store brands. But with certain products I am very brand loyal (even when my budget tells me to be otherwise).Do you have brand loyalty with certain household products?

The American Marketing Association defines brand loyalty as when " a consumer generally buys the same manufacturer-originated product or service repeatedly over time rather than buying from multiple suppliers within the category." And "the degree to which a consumer consistently purchases the same brand within a product class"

Here is my breakdown. Please add yours in the comment section!

Brand Loyal:
• Bounty Select-a-Size paper towels (I love how you don't have to use a huge piece for tiny uses),
• Ziploc brand plastic sandwich and food storage bags (the others just don't do the trick),
• Glad kitchen trash bags
• Breville toasters and kettles
• Colgate toothpaste (the kind that stands up).
• Windex brand window cleaner

Partially Brand Loyal:
For many things I am generally brand loyal but willing to experiment to save money:
• Sheets (love Restoration Hardware's hotel sheets but have strayed from the brand once or twice)
• Soap (usually get Dove but will try others as long as they contain moisturizing creams)
• Cat food (usually Whiskas pouches but not always)
• Diapers (usually Huggies but not always)

No Brand Loyalty (Always buy the cheapest--typically generic or store brand):
• pantry items (salt, flour, sugar)
• batteries
• gasoline
• over-the-counter medications
• bleach and countertop spray

What products have won you over to the point that you have tunnel vision when you walk down the aisle?
• House paint?
• Cleaning products?
• Paper goods?
• Toiletries?
• Small appliances?
• Hardware store items?
