I'm in a Chicago burb and cannot find any vg other than the 2oz wiltons. I have tried everywhere cvs, walgreens, walmart, gnc etc..., nothing. (Same goes with the Lorann's). I'll try asking to order at walgreens tomorrow, or order online. I just find it hard to believe in such a large market none is available retail. (off topic: all the blue foam is sold out also, 8 pet stores)
Wilton's is fine and is the same as Humco Glycerin.
