Hi there! Regarding the 3600 coupons back, tho im not sure if my knowledge is correct .. you cannot get the 3600 coupons in whole, thus you can get particular amount of coupons per day which you can claim in the Benefit Hall .. Please correct me guys if im wrong, i never tried to activate a medal :|

You get 20 coupons each day for 180 days which gives you 3600 coupons total.

Hi there,

Exvius is correct, you received 20 coupons everyday upon sign in from the benefit hall which totals 3600 coupons over the 180 days
