The company has yet to find success at sea, the last attempt being foiled by a wonky landing strut. And it doesn't look like this time will be much better. According to the SpaceX press release, "given this mission's unique GTO profile, a successful landing is not expected.​" The delivery will launch from Cape Canaveral, Florida during a 90-minute window starting at 6:45pm Eastern.

Update: SpaceX tweeted that it is holding the launch for today, and will try again tomorrow, at the same time of day.
