"Its normal price should be 20 coupons/ingots and not 10 coupons/ingots"

it seems to me that since i've been playing, it's always been 10 coupons and it should cost 10 coupons since it only gives 1 food piece! So i want at least the price reduced back as it was before. Cause not only i didn't get sakura/sasuke, now i can't even get other stuff cause the price is doubled?? Wtf! Also, some sakura packs or naruto ramen packs and seal scrolls.
