I literally have it on amazon right now: https://www.amazon.com/33/dp/B002HGVUB8/ref=sr_1_3?s=movies-tv&ie=UTF8&qid=1490796747&sr=1-3&keywords=battlestar+galactica&refinements=p_n_format_browse-bin%3A2650306011

Weird. Yours sends me to the Season 1 of the show and not the mini-series. What do you see on your end?

The links are different too:

yours:

https://www.amazon.com/Battlestar-Galactica-Season-1/dp/B002HGVUB8

mine:

https://www.amazon.com/Battlestar-Galactica-The-Mini-Series/dp/B002VEG2DM/ref=sr_1_1?s=instant-video&ie=UTF8&qid=1516735770&sr=1-1&keywords=battlestar+galactica+miniseries

https://www.amazon.com/gp/aw/d/B002HGVUB8/ref=mp_s_a_1_1?ie=UTF8&qid=1500485137&sr=1-1&pi=AC_SX236_SY340_FMwebp_QL65&keywords=Battlestar+Galactica

And because Amazon can't be bothered to link the miniseries to the rest of the first season here ya go: https://www.amazon.com/Battlestar-Galactica-Season-1/dp/B002HGVUB8
