There are five different types of consumer products: convenience, shopping, speciality, emergency and unsought.

Convenience products are those which consumers tend to purchase everyday. Examples of these products are food and personal hygiene products.

Shopping products are those which consumers make after deliberate consideration and comparisons. Examples of these products are clothing and electronics.

Speciality products are those where the consumer makes a special effort (as denoted by the word "speciality") to make. Examples of these products are luxury automobiles and cigars.

Emergency products are those which a consumer did not consider needing, but has come to need it (without planning). Examples of emergency products are car repairs and funeral planning (for sudden deaths).

Unsought products are the products which the consumer does not know that they want. These products are those which the consumer does not consider on a regular basis (like life insurance or burial plots).

Therefore, the products in question (watches, automobiles and toothpaste) fall into the following categories.

Watches can be considered as either a shopping product or a speciality product (depending upon cost and need).

Automobiles can be considered as either a shopping product or a speciality product (again depending upon cost and need).

Toothpaste is relatively straightforward. Toothpaste is a convenience product. Everyone buys and needs this product (in general).
