Not fully sure of what you ment, but you can get coupons for day you spent ingots + 6 days after. If you didn't buy froggy on 1st day, you should still get coupons on today. You got only days of 1st week to spend ingots in Froggy.

I did say, that you got only 1st week to spend ingots. 2nd week is only for claiming coupons you didn't get on 1st week, because you didn't get them on day 1. It seems you can't spend ingots anymore on today, if that's what you ment. Sorry.
