Ya, that’s a bit unfortunate, but not surprising - Paizo want people paying full price for the remastered content right now.

I’ve purchased Abomination Vaults, Age of Ashes, and Outlaws of Alkenstar, but have only played AV so far. The Foundry modules are worth the money alone as they make GMing that much easier. There’s a fair bit of overlap between the bundles, especially at the lower tiers (which is by design), but it’s still an incredible deal.
