Buyer request to delay shipment after purchase

Hi All,
Unless I'd missed something, there doesn't appear to be a dedicated forum thread to discuss the nuts and bolts of selling/buying on AG, so I'm posting here.

I have a potential buyer who'd like to make a purchase, but would like shipping delayed for a couple weeks while he's on vacation. This doesn't sound like it would be difficult to do, but I've not yet handled a similar request, so I'm wondering what's the best way to do it. Thanks and appreciate the help!
