As titled! New player here, I was grinding battling and got a lot of tear crystals in my inventory and it's kind of a pain moving them one by one to the vault. Wondering if there's a mass move option?

If you have a shop or gallery, you can use the quickstock feature (hover over "commerce tab" > your shops > (qs) by the shop name) to mass move things to your vault

Thanks! Ah so the issue with that is, when I click "your shops", it shows I have no shop and no "create new shop" or anything alike. Is there a link where I can create a new shop/gallery?

There should be a "create shop" button if you enter the "your shop" page.
