Credit cards + overdraw feature == bad!.
I got my server payment delayed (so I thought) however instead of just the transaction failing, no the payment goes through. Lucky my bank doesn’t charge me any fees if I balance the account back quickly (most unfortunately do), but it now leaves me with having to get extensions to bills almost due.
And hopefully getting the overdraw feature disabled if possible.
So, if you have a CC or thinking of getting one, make sure you have no overdraft feature!
