customers have differing expectations of quality. some expect the highest quality whilst others are satisfied with less e.g. someone who spends £4 in morley’s will have lower expectations than someone who spends £40 in a gourmet restaurant
price
lowering prices increases sales. the price that customers are willing to pay depends on the value they place on the product.
choice
customers love to have a choice because we all have different tastes
and needs. e.g. maccies provides a variety of choices on its menu such as beef, chicken and veggie choices served in a variety of ways
convenience
if businesses can make life easier for customers, then they are more likely to meet their needs e.g amazon offering next/same day delivery
