Can I buy TGIF restaurant's pre-made Brandy Alexander mix at a liquor store?

I just love TGIF's frozen brandy alexander drinks, but I don't always want to go there just to have one. I would think that they would have it pre-made for the public to buy since TGIF do have products in some grocery stores such as frozen appetizers, and I have seen some TGIF pre-made drinks in liquor stores, but I don't think I have seen the brandy alexander mixes. Does anyone have an idea if they do sell them? Thanks
