Before jumping on BO as taking orders they know they won't be filling, I'd let this shake out a bit.
I certainly hope that's not what is happening, and it could be.  I'd be chasing a charge back if I had made a purchase, but it might also be an algorithm that wasn't shut down that is excepting orders.
I might be incorrect, but the merchant will usually need to confirm the order once shipped which is what ultimately charges the account.  Usually its a hold. 
This is a loose translation from someone with some basic understanding of how CC services work.  And is likely a bit different depending on which card service you use in your business. 
Just saying it might be a bit early to be gathering the marshmallows, Hershey, and graham crackers.  
As a supplier, depending on how you ran your accounts, you might be SOL.  If you were doing a net30 I'd be getting in line for the settlement of debt.  Hopefully you were a secured supplier, however thats not too common, especially for smaller mom and pop type businesses getting their products out there.
