I ordered my Blackheart little giant amp from the musicstore.de online shop.
But I placed the order like a week ago and couldn't transfer the money till today because of carnival...

So .. how do they know that I payed ? since they don't ask for my bank account number on the site.

(i'm from the netherlands... if that matters)

Thanks in advance

Usually, they will be notified of payments to them, electronically, which will match up with their outstanding invoices and clear the transaction for processing/shipment. Different companies work different ways and I have not dealt with musicstore.de but that is how Thomann work.
I pick up my guitar and play
