If you are considering setting up a vending business in Chocolate / Crisps etc ....It is not going to be possible to compete with the likes of Aldi/Lidl nowadays .
It was even on the Six-one News this evening , that people are not shopping for convenience anymore , but are shopping for keen prices.
The likes of Lidl often do not sell the brands that people want. Also, if you want a little something for say a euro at / after college, at a train station, after the swimming pool etc ...are you going to try to find a Lidl ?
