After finishing the Traveler's Journal tasks, a new game activity has been launched, the Trading Shop. Perhaps this is due to a bug that allows you to "keep" transmogrification options for yourself. Coupons will be returned to players when the game restarts; some players don't receive the monthly bonuses, Ash'dara, this problem will be resolved this week.
Many players feel that some of the issues have already been resolved: they were given back vouchers and a unique mount. In February, Dragonflight can be purchased for a total of 2000 coupons, which will be reduced to 1000.
