Q:
Wintersday 8000 gem purchase bonus
A:
“In early January, you will receive your gift based on gems you purchase and gem codes you redeem between 12:01 AM December 1 and 11:59 PM December 31 PST.”
Taken from https://www.guildwars2.com/en/news/introducing-the-black-lion-wintersday-rewards-event/
you don’t get the gifts until early january , this is because you don’t have to buy the gems all at once but between the dates given
You get them next month.
Thank you very much guys
