Where do you live? I'm in the midwest, US, and theoretical savings between 2x and 5x amounts to a single full bag of groceries. Literally.

How can this possibly be a concern?

You are clearly overpaying for your groceries. I can cook for a week from the difference.

If there wasn't a significant difference, they would offer 2x Max, the demand is there. But they don't. Clearly, their strategy works on fanboys like you.

Same here. I'd love a 2x Max plan! More than enough usage for my needs.

Just make two plans and switch, when one of them is exhausted.

Yes, I hear that is what people do. Annoying though.
