Sending jackets by credit card is a common promotional activity. Banks or credit card companies attract more customers to apply for credit cards by giving away jackets. Under normal circumstances, as long as the customer handles the credit card according to the activity regulations and fulfills the corresponding conditions, he can get the jacket as a gift. This kind of activity is recognized and authorized by banks or credit card companies, so it is more reliable. However, customers should read the activity rules carefully before participating in the activity to find out whether there are any hidden restrictions or conditions, so as to ensure the smooth acquisition of the coat.
