DMsGuild is having a Black Friday sale: https://www.dmsguild.com/blackfriday.php
33% off digital downloads of selected titles. It's going until 10 am Tuesday, if my math is right (3 days and 7 hours from now).
Includes some official 5e stuff by WotC like the Wayfinder's Guide to Eberron, the Tortle Package, and One Grung Above - as well as a bunch of AL adventures.
