When a company makes artisan soaps and sells them individually, they have their 1st product.
When they cut the soap in half, repackage it, and call it a “Traveller’s Pack”, they have their 2nd product.
When they cut the soap into the shape of little animals and call it a “Kid’s Fun Size”, they have their 3rd product.
When they put different types of soap together, put them into a nice basket, and call it a “Gift Basket”, they have their 4th product.
When they package a few bars of the same soap together, lower the total price a bit, and call it a “Family Value Pack”, they have their 5th product.
Same soap, but five different products serving five different needs.
