Since it hasn't been mentioned let's just put it on the table here that Amazon Prime, a service with a fairly steep annual fee, supposedly came with a promise of two-day shipping, in exchange for that fee.

Now if there was some fine print I didn't read, shame on me, but has Amazon explicitly addressed this?

I do understand that the physical items themselves are in short supply and cannot be instantly produced by any kind of magic. (Although as an aside, and it's really not my main point, but I do think Amazon has the buying power to incentivize many suppliers to move mountains).

Just like the physical items, the money to pay the fee for Prime memberships can also correspondingly go into short supply as well, and individual members may have good reasons to stop paying if they aren't getting what they paid for.

Certainly facts on the ground have changed the deal. Maybe we Prime members will just be in the front of the line for frequently hoarded items... sigh. Will be interesting to see how Prime fares through this.
