Did you push them into the Internet Archive yet? If not, going to grab a beer and start iterating through your IPFS objects.
AWS will give you a whole year if you haven't tried them yet and the other popular VPS companies (DO, Linode, etc.) all will give you at least $10 startup credit. This is probably simpler and faster than figuring out how to receive <$4 from some random internet commenter.
Anywho, the amount of data is actually ~19GB which is well within what I can upload with my home connection. Unfortunately the ia tool is failing for me: https://github.com/jjjake/internetarchive/issues/176
Also, it's not really about the $3, more that a tonne of "$3" projects really add up over a year or so.
