How to use the credit card of Bank of Communications is the most cost-effective? Do you have time to go to the supermarket to buy things at half price or get points online? thank you
It is more cost-effective (not the most cost-effective) for Bank of Communications to spend 5% (except platinum card) or 10% (platinum card) in the designated supermarket every Friday, and so is the designated gas station. However, in addition to the new card, there is also a threshold, that is, spending over 3,000 yuan last month.
