What is a Market?

Defining a market, a market is defined as a group of people with a disposable income

• a regular gathering of people for the purchase and sale of provisions, livestock, and other commodities.

Market = Consumers

It is ill advised to go to a market without an understanding of your consumer, they may not be interested in your commodities. 

Seasonal
Something where sales are concentrated in a particular part of the year rather than being fairly even through the year. Gardening supplies and plants, and seasonal vegetables are examples of this.

Annual
An example of an annual market could be holiday seasons, like Christmas, Christmas decorations are sold once a year and prices don't vary. Another annual market could be festivals, they are once a year so the price can be bumped up

Captured
Captive markets are markets where the potential consumers face a severely limited number of competitive suppliers; their only choices are to purchase what is available or to make no purchase at all. an example could be a petrol station on a motorway, they can charge more as if you are low on petrol on a motorway, you either buy more petrol, or are stranded
