You can pick it up for a third of the normal price in an Indiegala bundle^NSFW that includes four other games. Bundle has another day left if you want to grab it for $10 USD. VNDB entry.
Totally worth it. There's also an art book coming out this year by Koume Keito. I've seen it in other languages, but it's finally coming to the English speaking west.

Official art today by Manga artist Koume Keito. This image is from his Spice & Wolf art book, which is finally being translated into English.
Here's the Amazon link if you're interested. I'm sure you can get it from other websites too, so look around if you don't want to give Bezos any more money.
