Yeah we've been dealing with the same. My only option has been to switch dog chow over to a Purina blend at Sam's. It's literally 29 USD as opposed to PetsMart at over 80.
This have looks fabulous to me, but there's no way I'm preordering. I don't have a lot of experience with Bethesda, but I thought the overall picture painted was a pretty gorgeous one. Hopefully they can deliver. That being said, I just started playing Fallout76 about two weeks ago, so I don't mind waiting until they work sone things out. Overall though, what they are promising looks incredible. Probably too good to be true :)
