But the question that remains in the head of every smart consumer: whether these discounts are real or just a marketing trick to persuade you into buying. And how do I know when not to miss a great buying opportunity?

Before the e-commerce age, consumers had to physically walk past many stores, enter, and ask about the prices and then compare. And this was a very tiresome activity.
Today, in a couple of minutes, any consumer can browse many different shopping websites and compare the prices and the specifications for each product.
In fact there are Turkish websites that specialize only in comparing prices for the same product in different shopping websites, allowing the consumer to buy at the cheapest price with ease.
