I would say the FM in this case was unreadable. “starting at $0.011 per gigabyte”, "learn more" - no one would expect to pay $150 here.
As far as I see, in all other places they specify their pricing "per GB", and only this small phrase uncovers real meaning, which is not per actual GBs you transferred, but your peak rate multiplied by number of hours in month. IMHO this should be one of the first phrases describing the pricing model.
If you want more than 5% of your data in a month, the minimum it will cost you is $0.011 per gigabyte. Click here to see how to work out how much it will cost.
It's certainly not unreadable, although to be fair, it's nowhere near as clear as it should be.
'Use Amazon Glacier, it costs about a cent!' is the essential pitch.
