what if

Ya know, if you can figure out the answer to that question, you dont deserve to have a debit/check card. Use some common sense.

If you have a negative balance in your bank account, then you shouldn't order something online giving the details of that bank account. Your negative balance will increase and you may incur heavy fees for the same.

From this post and your other post, it seems to me that you may have been aware that those checks/money orders you collected were fraudulent and that you continue to try to figure out other ways to defraud your bank.

You're heading down a scary road. Good luck
