Suica and NEX card confusion?

Question:

I'm confused about the Suica and NEX rail pass.

The NEX pass is only good for the trip from Narita Airport into Tokyo is that right?

And the Suica card is good for all other subway, trains and buses in Tokyo (except for Shinkansen) right? But what's the 1500 credit on the Suica card? Does the subway fare get deducted from this 1500 credit or is this just to buy items in snack machines and/or shops?

And on the JREast website it says that you can't buy the Suica & NEX overseas, so does that mean I have to wait to buy the pass there? What happens if the NEX is all booked up?

Any advice would be appreciated. :-)

Answer:

Let me clear it up for you:

It is a Suica & NEX deal.

You get a SUICA CARD and a NEX TICKET.

You use the NEX ticket to ride the Narita Express train from Narita Airport to whatever JR station you want in Tokyo.

You use the SUICA CARD for any other train travel you do. This can be JR trains, subway trains, buses, whatever.

The Suica card has 1500yen loaded onto it, each time you ride the train, subway, buy something at a vending machine, store etc and use the card, money is deducted (like a debit card) from the Suica card. How much money deducted depends on the cost of the train ride or the thing you are buying. If you run out of money, you recharge the Suica card at any vending machine.

You buy the Suica & NEX package IN Japan, they need to check your passport.
The NEX RARELY sells out. If it sells out, then get on the next NEX train, or take an airport limousine bus, or take an alternate train like the keisei skyliner into Tokyo. Again the NEX rarely sells out, so it's not something to worry about.
