Sales are everywhere. Sale on shoes, bags, shirts, gadgets and everything. Malls and shops use this technique to attract buyers, but you know what? Do you think you've been discounted a higher price than ordinary? No. Instead of saving 20%, you spend 80% on things you dont really need. This is not economical and most of us are easily lured to it. This is what i hate about people. When there's useless trending items on sale, they buy immediately even on credit cards but if bitcoin drops, they talk negative about it. Normal mindset wants to get temporary attention. Not permanent comfort.
Sale is a marketing technique and I have never at all believed. I have worked in a shoe store and the way we attract buyers is to do SALE (Discount), ranging from 20% to 70%... our trick is to increase the price of the item by as much as 50% then give it a 70% discount, so actually, we only give discounts of as much as 20%. the point is sale is a marketing trick.
