Agree with the others. Main questions are...
How many pounds of rock? Nail them down on that. You're looking for 100-140 lbs for that size tank.
Agree that while the skimmer is a decent one, it's undersized for the tank. My skimmer is rated for a tank twice my size. Doubling up on the capacity seems like a good deal.
The lights are Coralife. Their "other" name is "Energy Savers". Same with the thermometer. Your LFS
understands their competition because the price on the lights are about the same as you'd get on the internet. Oh... and they're PC
lunar lights. Nice lights for low-medium light LPS
corals, (as well as soft corals, mushrooms, and zoanthids) in my opinion.
Agree that you'll want a refractometer not long after you start trying to use the hydrometer. Might as well go that way to start with. I notice they're not throwing in any test kits. You're going to need the basics when you cycle - pH, ammonia, nitrite, nitrate and then you'll probably want phosphate, calcium, and alkalinity once you get up and running.
While it seems like a good package deal, I'm sure that if you did your homework, and put together your own package, you could spend the same amount of money and get "more" for your money.
[edit: Oh... also seems like the heater is a little undersized for your tank size. Unless you live somewhere that it's always warm, 200W for 72g seems small. I have 2x 100W heaters on my 46g and it seems just right. House temp varies between 70 and 64 during the winter, and 70-80 during the summer.
Also... they didn't include any powerheads for water movement within the tank. The return pump alone isn't going to do it.
Oh... and the filter sock (16"/100 M. Bag w/draw string(what is this?) $11.99) is a thing that goes over the inlet to your sump to keep the big gunk from getting into it and going through your return pump.]
