im thinking of canceling few of my credit cards to save the RM25 in the future. some of the cards i never use them, only applied to get free gifts.

CIMB Cash Rebate Platinum (RM5000 limit)
-used for petrol and telco bill

Maybank Ikhwan Gold (RM6000)
-used for petrol on weekend

Public Bank Quantum Visa
Public Bank Quantum Mastercard.
-combine limit of RM7,500
-never used

Public Islamic Platinum Visa (RM7500)
- never used

Ambank Islamic Al Taslif Platinum (RM10,000)
Ambank Carz Platinum (RM10,000)
-never used
- is it combined limit?

The cards that i always used are CIMB & Maybank only but their limit is low.
any advise?
Thank you.
