I just bought the eight Christmas items from D&D Beyond. I was just wondering when they get added on there cause I just went to check and I don’t have anything for the 12 days of Christmas thing.

My stuff showed up after completing the sale.
The documents appeared in sources right away, the dice set needed me to refresh the dice collection page.
If that doesn't work out, maybe try looking in your account if these appear in your licenses and if all entitlements are in sync.

Yes, as long as you have an account. I don't have a paid account and I was able to put the one of those that I didn't have, the uni module, in my card and purchase it for free. It's not like last year where you just clicked on a link. Three of the four of them were definitely available for free previously https://100001****/ https://1921681254.mx/ .

You should get an email with keys to redeem your free gifts you just have to go enter the keys on the link they provide. 

I still haven’t gotten any of the things I bought I checked licenses and I looked in dnd beyond again and nothing is there

None of the dices has been added for me. One of the books seemed like it hadn't been added either. Or at least I think I have gotten the books. But as there isn't a good way of seeing which books you own, on this site, I have to use the app. It just shows what a joke it is, and how poorly this site is designed. In the app, it will also show shared, as own, so you have to look for that small text, on each of the books listed under owned

I haven't gotten that

I sent and email to support and they sent me my codes and also told me they would prolly have been in my spam trash or promotions tabs or something like that.

I went back and added them again. Then I got them. It must not be able to handle so many items (I didn't learn about it, until there was 9 items)
