in events when fukurokumaru deals is on going

Kind of late response but as someone else said in a previous reply fukurokumaru event mostly happens every month. Every fukurokumaru event c*so be different most of the times the rebate is for 35k coupons but there's also the possiblity of it being 60k or 110k so best is to just save for couple of months till you hit 35k and see when fukurokumaru event comes around if it's 35k and if so you can spend into events and get rewards from the event. And there's not really any alternative event compared to fukurokumaru event as it's the only event where you get rewards for spending coupons.
