When did Lindt get so expensive?

Lindt has always been expensive in Japan, but I don't remember it being this expensive: 150 yen for just one of the small Lindor Lindt chocolate. There is a pop up shop in Kawagoe station today and when I saw the banner I went over to buy some. I love Lindt chocolate. But when I saw it was 150 yen for just one of the bite sized 'Lindor' Lindt I decided not to indulge after all!

I think 150 yen seems a bit extreme -or is that just me? I know everything has gone up this year, but you have to draw the line somewhere. However, they did have large packs with 50 Lindt chocolates on sale. It normally costs 7500 yen for the large pack with the bite size Lindt balls of chocolate, but they were selling them for 5800 yen today.

As much as I love Lindt chocolate I wouldn't eat 50 of them! I know the kids would have helped me, but still. However, if they had smaller package available at the price for 50 - one chocolate for 116 yen - I would have bought one. But I couldn't really justify 5800 yen for 'just' chocolate. (Especially as I'd just bought limited edition Mister Donuts!)

I am curious now how much they've gone up in the last year. Its a long shot, but does anyone know how much the Lindor Lindt were two years ago?
