Fair Trade charities try to make sure the farmers get the best price for their crops in the poorer parts of the world.
Make Trade Fair has celebrity supporters such as Coldplay's Chris Martin and U2's Bono.
The Fairtrade Foundation's chocolate bars include Dubble and Divine - as well as other products like coffee and bananas.
Currently, more than 200 coffee, tea, banana, chocolate, cocoa, juice, sugar and honey products carry the Fairtrade Mark.
