How long does fermented cod liver oil and butter oil keep for unopened?

[Sieren]

Green Pasture is having a sale, and I was thinking of stocking up on both of these.  Each bottle lasts us about a month and a half, and I was going to get 3 of each fclo and bo.  If I keep them all unopened in the fridge, will they last several months?  Thanks! ;)

well isn't this a coincidence.... I just came on to ask this exact question a year later!! lol :-)

I'd still like to know, as I have some left from the last sale :-)
