Treasury Minister Alf Cannan has defended keeping information out of the public domain when taxpayers' money's being spent.
In the House of Keys this week he faced calls from Onchan MHK Julie Edge to scrap commercial confidentiality clauses in government contracts.
Mr Cannan said if people wanted the information, they could use the Freedom of Information Act to apply for it - although that can also block releases because they contain commercial data.
And he said it was right government could keep prices secret:
MONEYVAL reps visit to give guidance for Island's major assessment
Window Wanderland to return soon
Motorsport event appealing for marshals
Rural road's poor condition closes it for weeks
50-mile Ultramarathon to launch in Island
Another yellow weather warning for coastal overtopping
Dental practice to relocate once more
Weather cancels two ferries today
