Redundant expressions and phrases that, when you stop to think about it, people really don’t need to say because they reduce the average intelligence in the room.

Free gift
Often used in advertising as a way to encourage the purchase of a high-ticket item by offering an incentive, in many cases, a lower-priced product or service. While I understand that using the word “free” is a marketing technique to increase appeal, using it in conjunction with the word “gift” makes the expression redundant. A gift is by its nature, free because if there is a price, it is not a gift. [2015-12-13]
