Where can I find a coke Icee in Houston?

I realize this is not essential, but I’m pregnant and have been craving an Icee since the pandemic started. I know they sell them at Target but I’m assuming the food areas have closed down. Does anyone know where I can send my husband to find one? If I can’t drink heavily during this time, I might as well find joy in other, nonalcoholic things. THANK YOU in advance!
