It actually happened to me, actually more than once on drastically changed designs. I buy the same thing I had at home, because I like it, and why change things that work?

At the store, I don't see it. I may notice that product with the same name, but the spell is broken, it is no longer the product I mindlessly buy again and again, and it may be a good occasion to try something else. Even worse, I may end up buying competing products that look more like the original design than the new design of the same brand.
