Missing a few Supplements on Store

[Filgaea]

I can't find anywhere in the store both Volo’s Guide to Monsters and Mordenkainen’s Tome of Foes.
I have scoured the shop directly here and on Steam and have found them, I did find one adventure linked with Tome of Foes, but not the supplement itself.

Can anyone help me with this? Have they been taken down from the shop, because I remember seeing them a few years back.

The publisher discontinued sales of both of those books, since the newer Mordenkainen Presents: Multiverse of the Multiverse replaced them, as it contains updated information from both books.

However, you if you already own one or both of them you can still use them.
