Just a heads up, the frackin' toasters at Prime Video inexplicably left out the excellent Razor movie, which came out between seasons 3 and 4. Also missing the Resistance webisodes from between seasons 2 and 3. Looks like Razor is rentable on Google for a fee, and The Resistance might be on Youtube, not sure of quality or completeness though.

Aside from those omissions, they do have the mini-series (as one long stream), 4 main seasons, and the Plan movie, all free with Prime Video, at least in the US.

The Blood & Chrome prequel movie can be streamed for a fee, and ditto for the single-season Caprica spin-off series.
