"Old" candy vending machine adjustment

[Michel99]

Hi,

I am new to this forum. I am from the Netherlands. And a boardmember of a small footballclub (soccer).

We have an old barstyle restroom for our members and the kids to socialize. We have a vendingmachine which takes 60 euro cents for a bag of candy or a snickers/kitkatt etc.

The prices of the candy have gone up so much that we would like to adjust the amount for payment. This is no standard option with this machine. Is there an easy way to modify the machine?

See pictures (you currently have to pay 1x 50cent and 1x 10 cent.

Kind regards,

Michel
