Just got this from Advanta, where I have a business credit card:
Your Advanta Business Card account is funded by an independent trust which owns the balances you owe on your account and provides funding for new transactions. We expect the trust to stop funding activity on our accounts. The trust also restricts our flexibility to fund activity on your account. Unfortunately, as a result, effective May 30th all Advanta Business Credit Card accounts, including your account, will be closed.
This means that you will not be able to use your card or account for new transactions, including purchases, checks and balance transfers beginning on May 30th.
I don’t use it much anyway, but it’s a little creepy not to have the choice.
