Davines shampoo

Braun S9 Pro electric razor

Cola Zero / Pepsi Max (generic alternatives rarely have sugarless options anyway)

Lipton probably but I can let it slip sometimes. Many alternatives just don't taste right, but they are at least drinkable.

Hair and skincare, especially since it's not even more expensive if I buy from a local store that sells those products in bulk.

I usually actually prefer the local knockoffs, it's usually better and uses locally sourced ingredients. Like soft drinks from the US taste sickeningly sweet and I really don't like them but there are plenty of locally made soft drinks that are great.

Bickford’s cordials. Whether with water or soda water, other flavours are just yuk.
