Where to buy Sweet Tooth Fairy meltables

I'm a treat maker and ran out of my dark chocolate which i use Sweet Tooth Fairy from Michael's, but I just went to one and they've replaced them with a different brand (can't remember the name) and the ones they have left are on clearance. I think they're permanently replacing the brand which sucks because it's the only store I know that sells them. Do any of you guys know somewhere else to buy them? I live in DFW, TX.
