Haggling is the process of negotiating the price of something (e.g. a piece of merchandise or a service) with the intent of getting a better deal than the stated price.

Although nowadays it is infrequently encountered in the West, it is still common (for example) in the purchase of used cars and sometimes for antiques. Some people report success in haggling for other things, such as the cost of having a chimney cleaned or the amount of a doctor's bill.

A particular combination of factors makes haggling commonplace in the UK mobile phone market:

• Market Saturation - The UK market is near saturation, meaning attracting new customers is primarily by converting customers from competitors.
• Sales Incentives - Mobile phone contract salespeople are often rewarded for customer retention and new contract signings.
• Telemarketing - Towards the end of fixed term contracts an 'upgrade' is often negotiated, usually over with a sales representative over the telephone; as opposed to pressured face-to-face sales where the majority contracts are signed. This non-contact makes customers bolder in their demands, with the added safety of knowledge of the above points listed here.

The dutch consumer show Ook dat nog! encouraged consumers to haggle more in different kinds of shops and hotels, and used a hidden camera to show that haggling can still be quite effective in western stores.
