Kitkat price in Narita Airport

I'm traveling soon and my stop over is in Narita Airport. I can't wait to get my hands on those famous kitkat flavors, I'm just curious how much they cost.

This is not airport price maybe close.

over 800Y are local limited sales version.

Yes, 800yen sounds about right. I snagged a box that looked like Mt. Fuji with Strawberry Cheesecake flavor. They also had Wasabi, Ichimi Hot Pepper, Apple, Plum, Strawberry and I'm sure a few others. They're larger than the regular little boxes of 3 packs, but the price sounds right at 800yen. Little Akihabara in T2 was where they had some and the "conbini" next to it had the rest. (as of 10/25/13)

Thanks! I saw a blog saying 1570 yen for a box of green tea kitkat containing 10 packs. I really hope its 800 yen..

I don't think the 10-pack box will go for 800yen. The 800yen ones are slightly larger versions of the normal packs. The 10-pak may fetch 1570yen. I don't remember too well as I was in a hurry to get on the plane and there were dozens of people in front of me in line.

Green tea(or Sakura-Maccha) flavor 2 pieces �~ 10 boxes for 1,570 YEN.
