Is this price fixed?

No, storage unit prices change based on usage of the Farcaster Protocol and Snapchain usage. FIP's will be created to signal the price of storage units.

What happens when your storage expires or you go over your limit?

If you go over your storage limits, hubs will start pruning old data immediately after around 60 minutes.

If your storage has expired there is a grace period of ~30 days to buy more storage after that Farcaster hubs will start pruning your older activity data.

Effects of this will be accounts you followed are no longer being followed and older casts of yours not being available.
