So you get 1 Suica point for every Y200 spent and need 10,000 Suica points before you can convert them to ANA. 10,000 x 200 = 2,000,000 yen, which is how much you have to spend on services OTHER than JR to get ANA points. Y2mil = US$25,200 at the current exchange rate, which adds up to a LOT of Mt. Rainier coffees bought!
In other words, why bother?
