What happened to the tequila kind??

So a couple of months ago, my grandma had my boyfriend and I over for tacos. She had your pace tequila (green) kind. Sorry forget what it is called. She said we have to try it it is excellent. So of course we both fell in love with it. We are not able to find it now in stores and I am soooo bummed out! We hooked others on it too and my phone has been ringing off the hook because they are no longer selling it. I don't even want to eat my tacos anymore because they just are not the same. Put that back on the market!!!!!
