Online retail services such as Amazon, Flipkart, etc., in many cases, fool their customers by manipulating list prices, to make discounts look bigger [COMPACTIDEA]

Whatever has been listed in these two articles appears not only deceptive and unethical, but also outright illegal. I have myself observed first-hand some tricks being played by Indian online retail services in order to fool the public. For example, if something was selling for INR 349 yesterday, and today you mark it down by just 1 INR [now INR 348] and label a flashy-looking "Deal of the day" tag on it, that's technically okay but practically useless and also unethical. Changing list prices, however, is altogether another level of fraud.
