> Google won't let me give them money to upgrade my storage
While not explicitly documented anywhere, they automatically increase your storage limits once you approach a certain margin of remaining free space. That happens around Tuesday-Wednesday, they just add extra 5Gb to your limit.
Any idea what sort of margin ballpark we're looking at? With a combination of email and Google Photos I got up to around 97% used a year ago and just had to move older photos elsewhere - would be good to test again if an increase will be given.
