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.
I think you are right in 99% of cases, but sometimes, and this applies primarily to the most expensive shops such as Dolce & Gabbana and Gucci, you can buy there a piece of clothes there with 90% discount, and it will cost you the same or even less than your regular shirt, but the quality of fabric will be so much better, you can't even imagine. I'm intentionally talking about fabric because I don't buy that "great design" shit and all, rich people so passionate about. And I'm not fantasizing either. My family, being far from a rich one, literally survived for some years because of such discounts in expensive shops. I mean, it's easier to find a job when you come on interview in Gucci or D&G, you know.
