I'd actually be willing to give it a try if it's vaguely price-competitive, but their website is all glam shots of butter and people doing things with butter and not only doesn't sell it but doesn't tell you where you can get it.
Also, they did not do a good job of choosing that name. It looks like there's a very-similarly-named French Canadian manufacturer of butter, Savör, which apparently isn't too religious about using their umlaut:
At Savor, we believe the best butter starts with the best environment. That’s why we source our grass-fed dairy butter from New Zealand, a country renowned for its pristine landscapes, sustainable farming, and exceptional dairy quality.
I foresee a collision between those two.
