Alright, the sales should be fixed and active. Everyone will also find up to 1200 Atlantean Shards in your item store claims (Under “Rewards”), in the form of six instances of 200 shards each. You may claim this up to six times total on any given account, but you can claim them on any character on your account.
For example, you could claim this three times on character 1 (for 600 shards), two times on character 2 (for 400 shards) and one time on character 3 (for 200 shards). Or all six on one character, if you want. Hopefully that makes sense.
This gift is available until January 8, 2021.
