## Definition

the market for parts, accessories, and repairs that you buy after you have already purchased the original product. It is common in the car and electronics industries.

For teachers: the secondary market for goods and services related to a primary product after its initial sale. Refers to the trade in replacement parts, maintenance, and enhancements.

## Examples

- The company makes a lot of money from the car aftermarket.
- While the initial sale of the printer was cheap, the company relies on the aftermarket for expensive ink cartridges to make a profit.
- A robust aftermarket for vintage watch components ensures that collectors can maintain their timepieces even decades after the original manufacturer has ceased production of specific mechanical parts.

## Usage notes

- Often used as a modifier before another noun (e.g., 'aftermarket parts').
