Where to find free parking lots in Singapore

Hi folks. Thought this is worth sharing, especially to those who drive. Saw this in the Straits Times:

Clarke Quay : Between 12pm and 3pm on Mondays to Fridays, excepts Public Holidays
Cold Storage Jelita Shopping Ctr : 1st hour daily from 830am till 10pm
Plaza Singapura : 1st hr from 10am to 6pm on Mon to Fri, except Public Holidays
Singapore Flyer : 12pm till 1:59pm - Mon to Fri, except Public Holidays
UE SQuare : Sundays and Public Holidays

Folks got any other parking lobangs to share? :)
