Brand loyalty

I think that if there is one product, or product line which will result in brand loyalty from consumers it would be laundry detergent and maybe dish soap. For certain laundry soap, I don't know alot of people who jump brands of laundry soap for price breaks, coupons, special offers and such. Its one of the products consumers won't sacrifice on. My ex was a firm sunlight user and I'm tide, we had to do separate laundry cause neither of us was willing to switch. I actually broke out in hives when she washed my stuff in her detergent (I might be allergic to the artificial lemon). My family as far back as I can remember has used tide, my mother, my grandmother. When we go overseas we brought tide with us to do laundry. We believe in the brand it has never done us wrong. when we change its within the brand line, We have all started using cold tide, and wont even look at any other companies cold detergent. Personally I know I bring up tide every time we talk about brand loyalty in classes, its the only think I believe I have loyalty to as a product.
