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.
LOL, this is called marketing strategy, the sales price is the actual price the retailer wishes to sell the product and whatever they add as it as extra is just a figure picked at random and not part of what makes up the price.
You know we are dealing with humans and for you to get attention of humans sometimes is quite stressful and really tasking, so one have to device lots of strategies. This is why we see that some exchanges too do inflate their volume in order to gain attention. This also happen in the ICO too. All those bonuses they give, all those hardcap and softcap quoted, aren’t they inflated?
