Affordable Carpark in Singapore??

Own a car is not difficult. Paying for carpark is a problem. You don't wish the IU beep too much while you drive.
Carpark in Singapore is expensive. Drivers constantly look out for free or cheap carpark.
So far, the more convenient and affordable ones (on Sundays) are ,
1. HDB carpark at Cantonment Close - free.. see this logo and smile :)2. ROM public carpark (If you go to Funan/ Raffles City) - free
3. Killiney Road Shopping Center (If you go Orchard) - $2.50 per entry
4. Winsland House (If you go Orchard) - $2.50 per entry
5. Shaw Center (If you go Suntec) - $2.14 per entry
Hopefully the list goes on...


Those to be avoided,
1. Center Point - $1 for 1st hour, $1.20 for subsequent every hour
2. Sg Flyer - $1 for every 30min. You are paying for the wonderful design. Take a few more glance!
3. Peony Jade @ Keppel - $2 for every 30min
