No. Not necessarily so. Besides, i thought you only have the PBB credit card with a credit limit of RM4k.
May be you can try to apply for the Maybankard 2 cards. For the Platinum one of course.

By the way guys, any idea which credit card companies that provide mail/parcel forwarding service for items ordered in US/UK if we pay using their credit card ? I only know a few banks providing such service. I am going to order something from the UK and i want to compare the shipping fees first.
- Citibank > Citi Globeshopper
- HSBC > vPost
- UOB > vPost
- Maybank > vPost
- Alliance Bank > vPost

By the way, shipments through vPost doesn't seem to incur any duty tax. Has anyone ever encountered problems such as your parcel being detained at the custom ? Please share your experience.
