Let me show you all how Elasticity responsive to Sales Promotion/Offer changes?

As we know Elasticity is to measure people responsive to the changes variables. Basically, we know that the 3 common elastic. (Elastic Demand, Inelastic Demand, Unit Elastic Demand). By using a market sales promotion will show us how people respond to it by using the 3 commons elasticity.

Firstly, we know that Luxuries Products are expensive and valuable. As a human, we know that if there is any offer in Luxuries Products we will grab it at the first place without thinking. Luxuries Products can be Shirts, Shoes, or even others. From the pictures below, we know that human react elastic to Luxuries Products by showing crowded.

Secondly, is Necessities Products which is cheap and can be get easily. Most of the necessities products can be found from any store. Example: Cold storage, Jusco, Tesco. When we saw offers on it, we mostly will not bother or care it. From the pictures below, we know how inelastic demand responds to necessities products, not even a single people.

From the novel above, we know that how elasticity happen and respond but it might not be same to everyone. So there are 7 different determinants of Elasticity by showing differently elastic demand. Luxuries vs. Necessities, Availability of Substitutes, Percentage of Income Spent, Price of the Product itself, Level of Income, Habits and Time period.
