Answer:
Dear Mr. Brown,
Thank you for your order, which we received today. We will be sending out your order as soon as possible. Currently, we are waiting for supplies to come in before we're in a position to send your order to you. However, we do expect these any day now and will send your order as soon as we are able to.
I hope you can understand our position. We thank you for your patience.
Thank you,
Sarah.
